Ensure your dog's safe surgical recovery by preventing infections with advanced strategies, expert tips, and effective post-op care

Surgical site infections (SSIs) are a major challenge in canine surgical care. These infections not only delay a dog's recovery but also increase treatment costs, extend hospital stays, and cause stress for both dogs and their owners. SSIs can affect surgical outcomes, leading to complications like delayed wound healing or systemic infections, which can even become life-threatening.
Preventing SSIs in dogs requires a proactive and careful approach. While following standard protocols like aseptic techniques and proper wound care is important, relying solely on these basics may not be enough. Advanced strategies, such as improved preparation, evidence-based irrigation methods, and innovative techniques, can greatly reduce the risk of SSIs.
In this article, we will explore basic practices along with advanced tools, such as non-antibiotic lavage solutions and innovative post-operative care measures, to ensure safer outcomes and faster recoveries for dogs. Preventing SSIs is not just about improving health; it's about setting higher standards in canine surgical care and maintaining the trust of dog owners.
Preoperative Measures: Preparing the Dog and the Team
When it comes to preventing SSIs in dogs, preparing both the patient and the surgical team is crucial. This preparation sets the stage for a successful surgery.
Patient Preparation
Proper preparation of the dog is essential to reducing the risk of SSIs. Clipping the fur is a key step and must be done carefully to avoid causing microtrauma. Always clip the fur close to the skin without shaving down to the dermis, as this can create tiny abrasions that allow bacteria to enter. Clipping should ideally be done just before surgery to reduce regrowth and contamination.
For antiseptic site preparation, chlorhexidine gluconate is considered the best choice in canine surgeries due to its wide-ranging effectiveness and long-lasting action. Povidone-iodine is another option, especially for dogs with sensitive skin. A two-step method—scrubbing with antiseptic soap followed by an alcohol-based solution—has been shown to be very effective in reducing microbes.
Surgical Team Preparedness
The surgical team’s adherence to aseptic techniques is equally vital. Proper hand scrubbing using chlorhexidine or iodine-based solutions, followed by wearing sterile gloves, is critical to minimize contamination risks.
Ensuring no breaches in gowning and gloving protocols during surgery is essential. Limiting movement and conversation in the surgical suite further reduces airborne contaminants, which is particularly important in high-risk procedures.
Prophylactic Antibiotics
Prophylactic antibiotics are essential in certain high-risk surgeries, such as orthopedic procedures (e.g., TPLO) or gastrointestinal surgeries, where the risk of contamination is naturally higher. However, using antibiotics too often in routine procedures like spays or neuters can lead to antibiotic resistance. Clear guidelines suggest giving antibiotics within 60 minutes before the first incision and stopping them within 24 hours unless there are signs of infection.
For instance, in TPLO surgeries for dogs, the proper use of antibiotics has greatly reduced post-operative infection rates, highlighting the importance of targeted prophylaxis.
Intraoperative Protocols: Ensuring Sterility Throughout Surgery
Every step we take during surgery to maintain sterility is crucial for protecting dogs from surgical site infections.
Surgical Site Integrity
Keeping the surgical site sterile is key to reducing SSIs. We aim to keep surgical time as short as possible to limit exposure to airborne contaminants. Careful handling of tissues is also important, as excessive manipulation can cause trauma and increase the risk of infection.
We ensure that instruments remain sterile throughout the procedure and reduce contamination by limiting unnecessary movement in the surgical area. Following strict aseptic protocols helps maintain the integrity of the surgical field.
Irrigation and Infection Control
Irrigation is essential for preventing SSIs, as it helps remove bacteria, debris, and dead cells from the surgical site. We use enough irrigation to thoroughly clean the area while being gentle to avoid harming healthy tissues.
Simini Protect Lavage is a popular choice for many veterinarians because its non-antibiotic formula helps reduce both bacteria and biofilms, which are major causes of persistent infections. Unlike saline, which only rinses away debris, or povidone-iodine, which can be harmful to tissues, Simini actively reduces biofilm and bacterial load without damaging tissue health.
Simini has been used in over 30,000 veterinary procedures and is endorsed by experts like Dr. Aldo Vezzoni, demonstrating its effectiveness in improving surgical outcomes.
Postoperative Care: Strengthening Infection Prevention Efforts
What happens after surgery is just as important as the procedure itself when it comes to preventing SSIs in dogs.
Immediate Postoperative Care
We must focus on careful wound management right after surgery to reduce infection risks. It's essential to ensure that wound closures are secure with high-quality sutures and protective dressings. Avoiding unnecessary disruptions, like frequent dressing changes, helps keep the area sterile.
During the first 24–72 hours, we watch for early signs of infection, such as redness, swelling, unusual discharge, or increased discomfort. Spotting these signs early allows for quick action, reducing complications.
Educating Dog Owners
Dog owners play a crucial role in the post-operative phase. Clear and practical instructions help them manage wound care at home effectively. We show owners how to clean the wound properly and explain how to prevent their dogs from licking or scratching the incision. Recommending tools like Elizabethan collars or wound protectors can greatly reduce risks.
We emphasize the importance of follow-up visits, as subtle signs of infection may only be detectable by trained professionals.
Advanced Tips for SSI Prevention in Canine Surgeries
To make infection control a routine practice, we should prioritize regular team training sessions. This ensures all staff understand and follow the latest evidence-based practices. Updating protocols as new research emerges is crucial, as our strategies must adapt to effectively address new challenges.
Investing in advanced tools can significantly improve outcomes. For example, Simini Protect Lavage has demonstrated its ability to reduce bacterial load and biofilm formation without added toxicity, setting a new standard in surgical irrigation.
Conclusion
Preventing surgical site infections in dogs is a team effort that requires attention, skill, and dedication to high standards. It involves working closely together, ongoing education, and using evidence-based protocols at every step.
Looking forward, adopting innovative solutions like Simini Protect Lavage can significantly boost our efforts to control SSIs. Its proven ability to target bacteria and biofilms without added toxicity makes it a breakthrough in veterinary surgery.
By sharing knowledge, updating protocols, and embracing new advancements, we can collectively improve surgical outcomes for dogs and ensure safer, healthier recoveries.

How Dogs Get Enterococcus faecalis
What is Enterococcus faecalis?
Enterococcus faecalis is a type of bacteria commonly found in the gastrointestinal tract of dogs. It is a commensal bacterium, meaning it lives with the body’s natural flora without causing harm under normal conditions. In a healthy dog, E. faecalis helps with digestion and maintains a balanced gut microbiome.
However, this bacterium can become opportunistic and pathogenic when a dog’s immune system is weakened or when there is an imbalance in gut bacteria. Factors like prolonged antibiotic use, chronic illness, surgery, or infections can disrupt this balance, allowing E. faecalis to multiply uncontrollably and spread to other tissues. When this occurs, it can lead to urinary tract infections (UTIs), wound infections, or more severe systemic infections.
Although usually harmless, E. faecalis can develop resistance to antibiotics, making infections harder to treat, especially in hospitalized or immunocompromised dogs.
How Do Dogs Get Enterococcus faecalis?
Dogs primarily acquire Enterococcus faecalis from their own gastrointestinal tract, where it naturally exists as part of the normal gut flora. However, under certain conditions, this bacterium can spread and cause infections in other parts of the body.
One of the most common modes of transmission is fecal contamination. If a dog’s feces contain E. faecalis, the bacteria can spread to the urinary tract, wounds, or other vulnerable areas through direct contact. This often happens when a dog grooms itself after defecation or comes into contact with contaminated bedding, floors, or other surfaces.
Environmental exposure is another route of transmission. Dogs can pick up E. faecalis from contaminated water, soil, or surfaces, especially in places like kennels, veterinary clinics, or dog parks. Shared water bowls, medical instruments, and poorly sanitized environments can all serve as sources of bacterial transfer.
Additionally, direct transmission can occur through licking, grooming, or ingesting contaminated food or objects. Dogs frequently use their mouths to explore their surroundings, making it easy for bacteria to spread. Immunocompromised dogs, those recovering from surgery, or those on long-term antibiotics are at a higher risk of developing infections from E. faecalis.
Risk Factors for Enterococcus faecalis Infections in Dogs
Dogs typically carry Enterococcus faecalis in their gastrointestinal tract without issues, but certain factors can increase the risk of this bacterium causing infections, particularly in the urinary tract and other vulnerable areas. These risk factors can be categorized into urinary tract-related factors and systemic conditions that compromise the body's natural defenses.
Urinary Tract-Related Factors
Several conditions affecting the lower urinary tract (LUT) create an environment where E. faecalis can thrive and cause infections:
- Recurrent bacteriuria – Frequent bacterial presence in the urine weakens the urinary tract’s natural defenses, allowing E. faecalis to establish infections.
- Lower urinary tract (LUT) anatomic abnormalities – Structural issues such as congenital defects or acquired conditions (e.g., urethral strictures) can lead to incomplete bladder emptying, increasing bacterial colonization.
- Urolithiasis (bladder stones) – The presence of bladder stones creates a favorable surface for bacterial attachment and biofilm formation, making infections more persistent and harder to treat.
- LUT neoplasia (tumors) – Tumors in the bladder or urethra can cause obstruction, tissue damage, and chronic inflammation, providing an entry point for E. faecalis to invade and multiply.
Systemic Conditions Increasing Risk
Beyond localized urinary tract issues, certain systemic health problems can compromise a dog’s ability to fight off infections:
- Neurologic dysfunction – Conditions affecting nerve control of the bladder (such as intervertebral disc disease or spinal cord injuries) can result in urine retention, which increases bacterial colonization.
- Endocrinopathies (hormonal disorders) – Diseases like diabetes mellitus and hyperadrenocorticism (Cushing’s disease) alter immune function and can lead to sugar-rich urine, which fosters bacterial growth.
- Urinary incontinence – Dogs with incontinence may have prolonged exposure to urine on their skin and mucosa, allowing E. faecalis to migrate from fecal contamination to the urinary tract.
- Corticosteroid administration – Long-term steroid use suppresses the immune system, reducing the body's ability to clear infections effectively.
- Chronic kidney disease (CKD) – Dogs with CKD often have altered urine concentration and immune dysfunction, making them more susceptible to urinary tract infections (UTIs) caused by E. faecalis.
- Urinary catheterization – Catheterized dogs, especially those requiring long-term urinary catheters, face a high risk of bacterial introduction into the bladder, providing E. faecalis a direct pathway to colonize the urinary tract.
Understanding these risk factors is crucial in preventing and managing E. faecalis infections in dogs. Regular veterinary checkups, proper hygiene, and addressing underlying conditions can significantly reduce the likelihood of infection.
Surgical and Post-Operative Infections Due to Enterococcus faecalis
How Surgical Infections Occur
Surgical site infections (SSIs) caused by Enterococcus faecalis can develop when bacteria enter the wound during or after surgery. Several factors contribute to these infections:
- Contaminated surgical tools or implants – If sterilization protocols are inadequate, E. faecalis can be introduced into the surgical site through contaminated instruments, implants, or sutures.
- Poor wound hygiene post-surgery – Inadequate wound care, improper bandage changes, or exposure to dirt and moisture can allow bacteria to multiply and infect the incision site.
- Exposure to multi-drug resistant (MDR) strains in hospital settings – Veterinary hospitals, particularly intensive care units, may harbor antibiotic-resistant E. faecalis strains that can cause difficult-to-treat infections in post-surgical patients.
- Pre-existing conditions like diabetes or immune suppression – Dogs with conditions like diabetes, chronic illness, or those receiving immunosuppressive therapy (e.g., corticosteroids) have a reduced ability to fight infections, increasing their risk.
Common Types of Infections in Post-Surgical Dogs
- Soft tissue infections – E. faecalis can cause swelling, redness, pain, and pus formation at the incision site, potentially leading to abscesses or delayed healing.
- Deep wound infections – When bacteria invade deeper tissues, infections can become more severe, requiring drainage, debridement, or antibiotic therapy.
- Orthopedic infections – Post-surgical infections involving bones, joints, or implants (e.g., TPLO plates) can be particularly challenging to treat, often necessitating prolonged antibiotic use or implant removal.
Preventing E. faecalis infections requires strict surgical asepsis, careful wound management, and appropriate post-operative monitoring to ensure proper healing.
Orthopedic Infections After TPLO Surgery and Enterococcus faecalis
Why TPLO Surgery Is at Risk
Tibial Plateau Leveling Osteotomy (TPLO) is a common surgical procedure for repairing cranial cruciate ligament (CCL) injuries in dogs. However, TPLO surgery carries a risk of post-operative infection, particularly from Enterococcus faecalis, due to several factors:
- Presence of surgical implants – Metal plates and screws used in TPLO surgery provide surfaces where bacteria like E. faecalis can adhere and form protective biofilms, making infections difficult to eliminate.
- Post-surgical inflammation and healing challenges – Normal healing involves inflammation, which can create an environment conducive to bacterial growth if E. faecalis contaminates the surgical site.
Complications Caused by Enterococcus faecalis in TPLO Surgeries
- Biofilm formation on implants – E. faecalis can develop biofilms on metal implants, creating a protective layer that resists antibiotics and the immune system, leading to persistent infections.
- Prolonged healing time – Chronic bacterial presence can delay bone healing, cause ongoing pain, and increase the risk of implant loosening.
- Increased risk of revision surgery or implant removal – If infection persists despite treatment, revision surgery may be necessary to remove infected implants and debride affected tissue, adding to recovery time and cost.
Preventing E. faecalis infections in TPLO cases requires strict aseptic techniques, post-operative monitoring, and early intervention if signs of infection arise.
Preventing Enterococcus faecalis Infections in Dogs
Hygiene Measures
Maintaining proper hygiene is essential in preventing Enterococcus faecalis infections. Cleanliness reduces the risk of bacterial exposure and helps keep your dog healthy:
- Proper cleaning of bedding, bowls, and living areas – Regularly wash your dog’s bedding, food and water bowls, and living spaces to remove bacteria and other contaminants. Disinfecting these items frequently is essential, especially in environments like kennels or vet clinics.
- Regular bathing and grooming – Keeping your dog clean through regular baths and grooming reduces the chance of bacterial buildup on their skin and fur, especially in areas like the paws or genital region, where bacteria can thrive.
Post-Surgery Care
Dogs recovering from surgery are at higher risk for infections like E. faecalis, and proper care can significantly reduce these risks:
- Keeping wounds clean and monitored for signs of infection – Gently clean surgical wounds as recommended by your vet and watch for redness, swelling, or discharge, which could indicate an infection.
- Following veterinary guidelines for post-op wound management – Adhere to all instructions regarding bandage changes, medication, and activity restrictions to promote healing and prevent bacterial contamination.
After surgery, keeping wounds clean and monitored for signs of infection is crucial. During surgery, advanced solutions like Simini Protect Lavage can be used by veterinary surgeons to minimize the risk of infection.
This non-antibiotic surgical lavage solution helps reduce bacterial contamination and prevents biofilm formation on surgical sites.
By using Simini during surgery, the risk of post-surgical infections is significantly lowered, contributing to faster, safer healing
Managing Underlying Health Conditions
Dogs with chronic health conditions are more vulnerable to infections, including E. faecalis:
- Regular vet check-ups for dogs with chronic illnesses – Regular veterinary visits help manage conditions like diabetes or kidney disease, which may predispose dogs to infections.
- Monitoring for early signs of urinary tract or surgical infections – Pay attention to symptoms such as changes in urination, discomfort, or poor wound healing, and seek veterinary care promptly if these signs appear.
By following these preventive measures, you can help protect your dog from E. faecalis infections and promote overall health.

How to Treat MRSP in Dogs: Best Practices
Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is a bacterial infection in dogs that doesn't respond to many antibiotics. It is related to MRSA (methicillin-resistant Staphylococcus aureus), which affects humans. MRSP often leads to skin infections, ear infections, and, in severe cases, deep tissue infections.
The biggest challenge with MRSP is its antibiotic resistance. Common antibiotics like penicillins and cephalosporins don't work against this bacteria. This resistance happens because of the overuse or misuse of antibiotics, making infections harder to treat. Treatment options are limited to specific, carefully chosen antibiotics or alternative therapies.
Signs Your Dog Might Have MRSP
Dogs with MRSP may show persistent skin infections that do not respond to regular antibiotics. Symptoms include:
- Red, inflamed skin with sores or pustules
- Excessive itching and hair loss
- Recurrent ear infections with discharge
- Slow-healing wounds
- Swelling or pain in the affected area
If your dog shows these signs, a veterinary diagnosis with bacterial culture testing is crucial for proper treatment.
Treatment Options for MRSP in Dogs
Home Care & Infection Control (Immediate Actions)
When dealing with MRSP, preventing the spread of bacteria is just as important as treating the infection. Since MRSP is resistant to many antibiotics, proper hygiene and containment measures can help protect other pets and humans in the household.
- Isolate the infected dog: Keep your dog separated from other pets to prevent bacterial transmission. MRSP can spread through direct contact, shared items, or contaminated surfaces.
- Practice strict hygiene: Always wash your hands thoroughly with soap and water after handling your dog. Use disposable gloves if treating wounds.
- Disinfect frequently used items: Clean bedding, collars, leashes, bowls, and any surfaces your dog touches using pet-safe disinfectants. Wash fabric items in hot water and dry them completely.
- Prevent self-trauma: Dogs with MRSP infections often scratch or lick the affected area, worsening the infection. Use an e-collar (Elizabethan collar) or protective clothing to prevent irritation and reinfection.
Proper infection control begins in the operating room, and if a veterinary surgeon uses an advanced wound irrigation solution like Simini Protect Lavage during surgery, it can help reduce bacterial contamination, including MRSP, lowering the risk of post-operative infections.
Topical Therapy (First-Line Treatment)
Topical therapy is a crucial first step in managing MRSP infections. Since MRSP bacteria live on the skin, direct application of antiseptics and antibiotics can help reduce bacterial load and promote healing.
- Antiseptic baths: Bathe your dog 2–3 times per week using an antiseptic shampoo containing 2–4% chlorhexidine. This helps kill bacteria on the skin and prevent new infections. Allow the shampoo to sit on the coat for 10 minutes before rinsing thoroughly.
- Mupirocin ointment: Apply twice daily to small, localized MRSP lesions. Mupirocin is effective against Staphylococcus pseudintermedius and helps treat infected wounds or hot spots.
- Topical amikacin spray: This antibiotic spray can be used once or twice daily to control bacterial growth in severe or widespread infections. It is often recommended when oral antibiotics are not an option.
Consistency is key—continue treatment for at least 2–4 weeks or as directed by your veterinarian. If symptoms persist or worsen, further medical intervention may be necessary.
Systemic Antibiotic Therapy (For Severe Cases)
Systemic antibiotics should be used only when necessary, as MRSP is resistant to many common antibiotics. Overuse can lead to further resistance, making future infections even harder to treat. In mild cases, topical therapy alone may be enough.
- Culture and sensitivity testing: Before starting any antibiotic, a veterinarian should perform a bacterial culture and sensitivity test. This identifies which antibiotics are effective against the specific MRSP strain in your dog. Treating without testing can lead to failed therapy and stronger resistance.
- Avoid beta-lactam antibiotics: Penicillins and cephalosporins are ineffective against MRSP and should not be used. This includes commonly prescribed antibiotics like amoxicillin-clavulanate or cephalexin.
- Alternative antibiotic options: Depending on test results, chloramphenicol, aminoglycosides (amikacin), clindamycin, or doxycycline may be prescribed. These are not first-line antibiotics and should only be used under veterinary guidance due to possible side effects.
Systemic antibiotic therapy typically lasts 4–6 weeks and requires strict follow-up to monitor effectiveness. If symptoms persist, adjusting the treatment plan may be necessary.
Duration of Treatment (How Long to Continue)
The duration of treatment for MRSP infections depends on the severity and depth of the infection. Stopping treatment too early can lead to recurrence, making the infection harder to eliminate in the future.
- Superficial pyoderma: This is a mild to moderate skin infection affecting the outer layers of the skin. Treatment with topical therapy and, if necessary, systemic antibiotics should continue for at least 3 weeks or one week beyond visible healing.
- Deep pyoderma: If the infection has spread into deeper skin layers, treatment is more intensive. Therapy should last 4–8 weeks or longer, continuing for at least 1–3 weeks after all lesions have healed to prevent relapse.
Why is extended treatment necessary? MRSP is highly resistant, and stopping treatment too soon allows surviving bacteria to multiply, leading to reinfection. This can also make the bacteria more difficult to treat in the future.
Regular veterinary check-ups and follow-up cultures help ensure the infection is fully cleared before stopping treatment.
Supporting Your Dog’s Recovery at Home
Diet & Supplements to Boost Healing
A nutrient-rich diet and targeted supplements can strengthen your dog's immune system and support skin healing after an MRSP infection. Proper nutrition plays a crucial role in reducing inflammation, repairing the skin barrier, and preventing future infections.
- Omega-3 supplements: Fish oil rich in EPA and DHA helps reduce inflammation and promote healthy skin. These essential fatty acids improve the skin barrier, making it more resistant to bacterial infections.
- Probiotics: If your dog has been on antibiotics, adding probiotics helps restore gut balance and support immune function. Look for Lactobacillus and Bifidobacterium strains, which promote good digestion and reduce antibiotic-related side effects.
- Hyaluronic acid sprays: Topical hyaluronic acid (HA) sprays enhance skin hydration and barrier repair, reducing irritation and supporting wound healing. They also help create a protective layer, preventing bacteria from re-entering the skin.
Feeding a high-quality, protein-rich diet with these supplements can help your dog recover faster and build long-term resistance against skin infections. Always consult your veterinarian before adding supplements to your dog’s routine.
Hygiene & Environmental Adjustments
Creating a clean, bacteria-free environment is essential to prevent reinfection and support your dog’s recovery from MRSP. Since MRSP can survive on surfaces, proper hygiene and environmental control help minimize bacterial spread.
- UV sterilization wands: These devices eliminate bacteria, viruses, and fungi on surfaces like bedding, collars, leashes, and food bowls. UV-C light disrupts bacterial DNA, making it an effective chemical-free disinfection method.
- Air purifiers with HEPA filters: MRSP bacteria can spread through air and dust particles. Using an air purifier with a HEPA filter helps capture airborne bacteria and allergens, reducing the risk of reinfection.
- Regular grooming: Keeping your dog’s skin clean is key. Bathe them with antimicrobial shampoos as recommended and brush their coat regularly to remove dirt, dead skin cells, and bacteria. Clean ears, trim nails, and check for any signs of skin irritation.
By maintaining strict hygiene practices and a clean home environment, you can lower bacterial exposure and help your dog heal faster.
Preventing Future MRSP Infections
Preventing reinfection is crucial for dogs that have recovered from MRSP. Since MRSP bacteria can persist in the environment and on the skin, consistent hygiene, early monitoring, and veterinary follow-ups are essential to keep your dog healthy.
- Regular bathing and hygiene: A weekly or biweekly bath with antiseptic shampoos (2–4% chlorhexidine) helps control bacterial levels on the skin. Regular cleaning of bedding, food bowls, and grooming tools prevents contamination.
- Monitoring for early signs: Dogs prone to skin infections should be checked regularly for redness, bumps, hair loss, or excessive scratching. Catching infections early allows for faster treatment with topical antiseptics, reducing the need for systemic antibiotics.
- Routine veterinary checkups: If your dog has a history of MRSP or recurrent skin infections, schedule regular checkups every 3–6 months. Your vet can perform skin cultures or cytology to detect bacteria before a full-blown infection develops.
By staying proactive with hygiene, early intervention, and veterinary care, you can significantly reduce the risk of future MRSP infections and keep your dog’s skin healthy.
When to See a Veterinarian
While home care and prescribed treatments can help manage MRSP infections, some cases require immediate veterinary attention. If your dog’s condition does not improve or worsens, a veterinarian can reassess the treatment plan to prevent complications.
- No improvement after 2 weeks: If your dog is receiving topical or systemic treatment but the infection persists after 2 weeks, it may indicate treatment resistance. A vet may need to adjust the antibiotic plan based on a new culture and sensitivity test.
- Worsening or spreading infection: If redness, swelling, or sores continue to spread despite home care, the infection could be deepening. MRSP can sometimes penetrate deeper tissues, leading to cellulitis or abscess formation, which requires stronger medical intervention.
- Systemic illness signs: If your dog becomes lethargic, refuses food, or develops a fever, the infection may have entered the bloodstream (sepsis) or caused a secondary illness. This is a medical emergency requiring urgent veterinary care.
Early veterinary intervention can prevent severe complications, ensuring a faster and safer recovery for your dog.

MRSP Infection in Dogs: Causes and Symptoms
What is MRSP Infection in Dogs?
Methicillin-Resistant Staphylococcus pseudintermedius (MRSP) is a type of bacteria that causes infections in dogs and is resistant to many common antibiotics, including methicillin and other beta-lactam antibiotics.
MRSP is a strain of Staphylococcus pseudintermedius, a bacterium naturally found on a dog’s skin and mucous membranes. While regular S. pseudintermedius infections can be treated with standard antibiotics, MRSP infections are much harder to manage due to their resistance to multiple drugs.
Unlike typical bacterial infections, MRSP does not respond to first-line antibiotics, making treatment more complex and prolonged. This resistance develops when bacteria are repeatedly exposed to antibiotics, leading to mutations that allow them to survive even in the presence of these medications.
MRSP is a major concern for veterinarians and dog owners because it can cause persistent skin infections, surgical site infections, and deep tissue infections. These infections are often recurrent and challenging to eradicate.
TL;DR
- MRSP spreads through direct contact, contaminated surfaces, and repeated antibiotic use, making multi-dog environments high-risk.
- Antibiotic resistance makes standard treatments ineffective, leading to persistent and recurrent infections.
- Infected dogs often develop skin lesions, swelling, non-healing wounds, and, in severe cases, fever and lethargy.
- Topical antiseptics and targeted antibiotics may help, but MRSP-related surgical infections remain difficult to manage.
- Simini Protect Lavage is the only effective non-antibiotic solution for MRSP surgical cases, preventing bacterial biofilm formation and reinfection.
How Common is MRSP in Dogs?
MRSP infections are becoming increasingly common in veterinary medicine, with rising cases reported worldwide. While Staphylococcus pseudintermedius is a normal part of a dog’s skin flora, the methicillin-resistant strain (MRSP) has been identified more frequently in veterinary clinics, kennels, and households with multiple pets.
Studies indicate that MRSP prevalence varies by region, but infection rates have increased due to widespread antibiotic use in veterinary medicine. Some research suggests that up to 40% of S. pseudintermedius isolates in certain veterinary hospitals show methicillin resistance.
Where MRSP is Commonly Found
MRSP is often detected in dogs with chronic skin conditions, post-surgical wounds, ear infections, and deep tissue abscesses. It is frequently seen in:
- Dogs with recurrent pyoderma or allergic skin disease
- Postoperative surgical site infections
- Dogs undergoing long-term antibiotic treatment
- Pets in shelters, kennels, or multi-dog households
Why Antibiotic Resistance is Increasing
The overuse and misuse of antibiotics are the primary drivers of MRSP resistance. Repeated exposure to antibiotics, particularly in cases where treatment is stopped early or used unnecessarily, allows bacteria to develop resistance.
Additionally, MRSP can spread between dogs through direct contact or contaminated surfaces, making infection control crucial in veterinary settings.
How Do Dogs Get MRSP?
MRSP is a highly resilient bacterium that spreads easily in veterinary settings and among dogs in close contact. Unlike typical bacterial infections that respond to standard antibiotics, MRSP thrives in environments with frequent antibiotic use, causing treatment-resistant infections.
Ways Dogs Can Contract MRSP
- Direct Contact with Infected Animals - Dogs can contract MRSP by coming into contact with another infected pet. This is especially common in multi-dog households, kennels, and veterinary clinics where animals interact closely.
- Exposure to Contaminated Surfaces - MRSP can survive on objects such as bedding, grooming tools, medical equipment, and kennel surfaces. Dogs that frequently visit grooming facilities, boarding kennels, or veterinary clinics may be exposed to these contaminated environments.
- Repeated Antibiotic Treatments - Overuse or misuse of antibiotics contributes to MRSP infections. When a dog is given antibiotics repeatedly—especially if treatments are stopped early—the bacteria can develop resistance, making future infections harder to treat.
- Weakened Immune System - Dogs with compromised immune systems, whether due to chronic illnesses, endocrine disorders, or stress, are more susceptible to MRSP. Their bodies struggle to fight off infections, increasing the likelihood of colonization by resistant bacteria.
Risk Factors for MRSP Infection
- Dogs with Allergies or Endocrine Disorders - Conditions like atopic dermatitis, hypothyroidism, or Cushing’s disease weaken the skin barrier and immune response, making dogs more vulnerable to MRSP infections.
- Frequent or Prolonged Antibiotic Use - Long-term antibiotic exposure alters bacterial populations, increasing the risk of antibiotic-resistant strains like MRSP.
- Extended Hospital Stays or Frequent Veterinary Visits - Dogs that require hospitalization, surgery, or repeated treatments are at higher risk due to increased exposure to MRSP-contaminated environments.
By understanding these transmission routes and risk factors, veterinarians and pet owners can take preventive measures to reduce the spread of MRSP and protect canine health.
Signs and Symptoms of MRSP in Dogs
MRSP infections primarily affect the skin but can also lead to deeper tissue infections. Since MRSP is resistant to many antibiotics, symptoms often persist despite initial treatments. Recognizing the signs early can help in timely diagnosis and management.
Common Skin-Related Symptoms
MRSP often presents as a skin infection (pyoderma) with visible lesions. You may notice:
- Abscesses or pustules (small pus-filled bumps)
- Redness and inflammation around the affected area
- Crusting or scabbing of the skin
- Non-healing wounds that worsen over time
Hair Loss and Excessive Itching
Dogs with MRSP infections may develop patchy hair loss (alopecia) due to chronic skin irritation. Constant itching, licking, or chewing of the infected area can lead to further skin damage and secondary infections.
Swelling, Pain, or Discomfort
Affected areas may become swollen and tender to the touch. If the infection spreads deeper, pain and localized warmth may be noticeable.
General Signs of Illness
If the infection becomes more severe, dogs may show systemic symptoms, such as:
- Fever
- Lethargy or weakness
- Loss of appetite
Since MRSP infections can mimic other skin conditions, a proper veterinary diagnosis is crucial for effective treatment.
Diagnosis: How Vets Confirm MRSP in Dogs
Diagnosing MRSP requires laboratory testing because it cannot be identified through visual examination alone. Since MRSP is resistant to many antibiotics, early and accurate diagnosis is essential for selecting the right treatment.
Culture and Sensitivity Testing
The most reliable way to confirm MRSP is through bacterial culture and antibiotic sensitivity testing. A veterinarian will collect a sample from an infected area—such as a skin lesion, wound, or ear discharge—using a sterile swab.
This sample is then sent to a laboratory, where technicians grow the bacteria and test its response to various antibiotics. If the bacteria show resistance to methicillin and other common drugs, MRSP is confirmed.
Why MRSP Requires Lab Testing
MRSP infections look similar to other bacterial skin infections, making it impossible to diagnose based on appearance alone. Without lab testing, standard antibiotic treatments may fail, leading to prolonged or worsening infections.
Importance of Early Diagnosis
Timely identification of MRSP allows veterinarians to prescribe the appropriate antibiotic or alternative treatments, reducing the risk of complications. Early diagnosis also helps prevent the spread of MRSP to other pets, especially in multi-dog households, veterinary clinics, and kennels.
How is MRSP Different from Other Staph Infections?
MRSP (Methicillin-Resistant Staphylococcus pseudintermedius) differs from typical Staphylococcus pseudintermedius infections in one key way: antibiotic resistance.
While both types of bacteria can cause skin infections, wounds, and post-surgical complications in dogs, MRSP is resistant to methicillin and many other commonly used antibiotics.
This makes it much harder to treat than regular S. pseudintermedius infections, which typically respond to first-line antibiotics like cephalexin or amoxicillin-clavulanate.
MRSP vs. MRSA: What’s the Difference?
MRSP is often compared to Methicillin-Resistant Staphylococcus aureus (MRSA), another drug-resistant staph infection. However, MRSP primarily affects dogs, while MRSA is more common in humans. Although MRSP can occasionally spread to humans, the risk of transmission is lower compared to MRSA.
Why MRSP is Harder to Treat
- Limited antibiotic options – Many standard antibiotics fail against MRSP, requiring veterinarians to use second-line or specialized treatments.
- Recurrent infections – MRSP infections often return after treatment, requiring long-term management.
- Environmental persistence – MRSP can survive on surfaces like bedding, kennels, and grooming tools, increasing the risk of reinfection.
Because of its resistance and persistence, MRSP requires careful antibiotic selection and strict infection control to prevent outbreaks in veterinary clinics and multi-pet households.
Are Certain Dog Breeds More Prone to MRSP?
Some dog breeds are more susceptible to MRSP due to genetic factors and breed-specific skin conditions. Breeds prone to allergies, skin folds, or chronic dermatitis have a higher risk of developing bacterial infections, which can lead to MRSP if antibiotics are overused.
Breeds at Higher Risk
- Bulldogs, Pugs, and Shar-Peis – Skin folds trap moisture, creating a breeding ground for bacteria.
- Labrador Retrievers and Golden Retrievers – Prone to allergic dermatitis and chronic ear infections.
- German Shepherds – More likely to develop deep pyoderma, a severe skin infection.
Proper skin care and infection prevention are key for these breeds.
Is MRSP Contagious to Other Dogs?
Yes, MRSP can spread between dogs, especially in multi-pet households, kennels, and veterinary clinics. It spreads through direct contact with infected dogs, contaminated surfaces (bedding, food bowls, grooming tools), and shared environments.
Risk Factors for Transmission
- Dogs in kennels, shelters, or veterinary hospitals
- Shared items like toys, blankets, or grooming tools
- Open wounds or skin infections that allow bacteria to enter
Can Asymptomatic Carriers Spread MRSP?
Yes, some dogs carry MRSP without showing symptoms but can spread it to others, making infection control crucial. Regular hygiene and isolation of infected dogs help prevent outbreaks.
Treatment Options for MRSP in Dogs
MRSP infections require a multifaceted treatment approach due to their resistance to common antibiotics. Treatment typically includes culture-guided antibiotic therapy, topical antiseptics, and infection management strategies to prevent recurrence.
Medical Treatments
- Antibiotic Therapy - Since MRSP does not respond to many first-line antibiotics, culture and sensitivity testing is essential to identify effective options. Some MRSP strains remain susceptible to chloramphenicol, doxycycline, rifampin, or amikacin, but each case requires individualized treatment.
- Why Some Antibiotics Don’t Work - MRSP carries resistance genes that make it immune to methicillin and other beta-lactam antibiotics, such as cephalexin and amoxicillin-clavulanate. Using ineffective antibiotics can worsen resistance, leading to chronic or recurrent infections.
Topical Treatments
- Antibacterial Shampoos and Solutions - Regular bathing with chlorhexidine or miconazole-based shampoos helps reduce bacterial load and prevent reinfection.
- Medicated Wipes and Ointments - For localized infections, antiseptic wipes, gels, or ointments (containing chlorhexidine or mupirocin) help control bacterial spread and promote healing.
The Role of Simini in Surgical MRSP Cases
For MRSP-related post-surgical infections, Simini Protect Lavage is a critical non-antibiotic solution. MRSP increases the risk of surgical site infections (SSIs), which can be difficult to treat with standard antibiotics.
Simini Protect Lavage effectively removes bacteria, disrupts biofilms, and lowers infection risks without contributing to antibiotic resistance. It is particularly beneficial for orthopedic surgeries, wound management, and post-operative care, where MRSP contamination poses a significant challenge.
For non-surgical MRSP infections, a combination of targeted antibiotics, antiseptic treatments, and strict hygiene measures is necessary to prevent recurrence and transmission.
Managing MRSP at Home: Infection Control and Prevention
MRSP can spread easily in multi-pet households, making strict hygiene and infection control measures essential. Since MRSP is resistant to many antibiotics, preventing transmission is just as important as treating the infected dog.
Strict Hygiene Measures
- Wash hands thoroughly after handling an infected dog, especially before touching other pets or household items.
- Use disposable gloves when applying topical treatments to avoid spreading bacteria.
- Limit direct contact, such as cuddling or allowing the dog to sleep on furniture, to prevent contamination.
Cleaning and Disinfecting
- Wash bedding, toys, collars, and bowls frequently using hot water and pet-safe disinfectants.
- Clean surfaces like floors and furniture with antibacterial solutions to eliminate lingering bacteria.
- Use separate grooming tools and feeding dishes for the infected dog to prevent cross-contamination.
Minimizing Spread to Other Pets and Humans
- Keep the infected dog in a separate space until the infection resolves.
- Regularly bathe pets with antibacterial shampoos if they share a home with an infected dog.
- Although MRSP is rarely transmitted to humans, immunocompromised individuals should take extra precautions when handling an infected pet.
Consistent infection control measures help prevent MRSP from spreading and reduce the risk of reinfection.
How to Prevent MRSP in Dogs
Preventing MRSP infections requires a proactive approach that focuses on responsible antibiotic use, regular veterinary care, and maintaining a strong immune system.
Since MRSP thrives in environments where antibiotics are overused or misused, reducing unnecessary antibiotic exposure is key to controlling its spread.
Responsible Antibiotic Use to Prevent Resistance
One of the biggest contributors to MRSP infections is antibiotic resistance, which develops when antibiotics are used improperly. To prevent this:
- Always complete prescribed antibiotic courses, even if symptoms improve before finishing the medication.
- Avoid using antibiotics without veterinary guidance, as incorrect treatment can promote resistant bacteria.
- If your dog has a history of bacterial infections, ask your vet about alternative treatments, such as antibacterial shampoos or topical antiseptics, instead of relying on systemic antibiotics.
Regular Vet Check-Ups to Detect Early Signs
Routine veterinary visits help catch skin infections, wounds, or other risk factors before they become severe. Early intervention reduces the chance of an infection becoming resistant to treatment.
Dogs with allergies, endocrine disorders, or chronic skin issues should have frequent skin assessments to monitor for signs of bacterial infections.
Strengthening the Immune System Through Diet and Hygiene
A strong immune system helps dogs fight off bacterial infections naturally. To improve immunity:
- Feed a balanced diet with high-quality proteins, essential fatty acids, and vitamins. Omega-3 and Omega-6 fatty acids support skin health, reducing infection risk.
- Maintain good hygiene by regularly bathing dogs with veterinary-approved shampoos to remove bacteria from the skin.
- Keep bedding, grooming tools, and food bowls clean to prevent bacterial buildup.
Prognosis: Can Dogs Recover from MRSP?
How Long It Takes to Treat MRSP
The duration of MRSP treatment depends on the severity of the infection and the effectiveness of treatment.
- Mild skin infections may resolve within 4-6 weeks with proper antibiotic and topical therapy.
- Deep or recurrent infections can take several months to fully heal, requiring a combination of antibiotics, antiseptic treatments, and strict hygiene measures.
- Post-surgical MRSP infections require specialized wound management, and in severe cases, additional procedures may be needed to remove infected tissue.
Chances of Recurrence and Long-Term Management
MRSP has a high recurrence rate, especially in dogs with underlying conditions like allergies, hypothyroidism, or chronic skin disease. Preventing reinfection requires:
- Monitoring for early signs of reinfection, such as skin redness, pustules, or excessive itching.
- Following hygiene protocols to minimize bacterial spread in the home.
- Using non-antibiotic alternatives like antiseptic washes and medicated shampoos to reduce bacterial load without contributing to antibiotic resistance.
When to Seek Veterinary Care for Persistent Infections
If a dog’s MRSP infection does not improve with treatment, spreads to deeper tissues, or recurs frequently, veterinary intervention is crucial. Seek immediate care if:
- Lesions worsen or new infections appear despite antibiotic therapy.
- The dog develops fever, lethargy, or loss of appetite, which may indicate a systemic infection.
- A post-surgical wound shows signs of MRSP, as these infections require specialized management to prevent complications.
With early detection, responsible treatment, and infection control, dogs with MRSP can recover and live healthy lives while minimizing the risk of recurrence.

Post-Operative Infection in Dogs: Symptoms and Solutions
Surgical procedures can save a dog's life or improve their quality of life, but recovery is just as important. Post-operative infections are among the most common complications after surgery in dogs. These infections can slow healing, cause discomfort, and in severe cases, pose serious risks to your pet's health. Knowing how infections occur, what signs to look for, and how to prevent them can greatly improve your dog's recovery.
As someone who has performed many surgeries, We want to share what you need to know to ensure a smooth and infection-free healing process. Let's understand how to care for your dog after surgery and prevent complications.
What Are Post-Op Infections in Dogs?
Post-op infections in dogs happen when bacteria enter a surgical wound, causing inflammation, delayed healing, and discomfort. These infections usually occur due to contamination during surgery, poor wound care, or a weakened immune system. Common bacteria involved include Staphylococcus, Pseudomonas, and Escherichia coli.
Factors like poor hygiene, excessive licking of the wound, or exposure to dirty environments increase the risk. Dogs with conditions like diabetes or obesity are more at risk because their immune systems may not fight infections well.
Statistics show that post-op infections in dogs occur in about 2% to 5% of surgical cases, depending on the type and length of the procedure. For more complex surgeries, like orthopedic or implant-based operations, the infection rate can rise to 8% or more.
Understanding these causes and risks is crucial for ensuring a smooth recovery for your dog after surgery.
Signs of Post-Op Infections in Dogs
Recognizing the signs of a post-op infection early can prevent complications and help your dog recover smoothly. Here are the symptoms to watch for:
- Redness, swelling, or warmth at the incision site: While mild redness is normal after surgery, excessive redness, noticeable swelling, or warmth around the wound may indicate an infection. This is often related to inflammation in the area.
- Pain, lethargy, or loss of appetite: If your dog seems unusually tired, uninterested in food, or shows signs of discomfort when the incision is touched, it could mean the wound is infected. Pain may result from tissue inflammation or an underlying abscess.
- Foul odor or discharge from the wound: Pus-like discharge—yellow, green, or bloody—and a bad smell are strong signs of a bacterial infection.
- Fever or abnormal behavior: A body temperature above 102.5°F, along with shivering, hiding, or restlessness, may indicate a systemic infection.
If you notice any of these symptoms, consult your vet promptly. Early treatment is crucial for your dog’s health and comfort.
Risk Factors That Increase the Chances of Infection
Certain factors make some dogs more likely to get post-op infections. Knowing these risks can help you take preventive steps.
- Pre-existing conditions: Dogs with diabetes, obesity, or diseases that weaken the immune system are at higher risk. These conditions slow wound healing and make it harder for the body to fight bacteria. For example, in diabetic dogs, high blood sugar can encourage bacterial growth, increasing the risk of infection.
- Longer surgery times: Longer surgeries give bacteria more time to enter the wound. Also, extended anesthesia can weaken the immune response, making the dog more vulnerable. Surgeons try to keep surgery times short while being precise to reduce this risk.
- Use of urinary catheters or preoperative shaving techniques: Catheters can introduce bacteria into the urinary tract if not handled correctly. Similarly, shaving the surgical site can cause tiny cuts, allowing bacteria to enter. Proper surgical protocols, like using clippers instead of razors and keeping a sterile environment, greatly reduce these risks.
Many of these factors can be managed with careful preparation and diligent post-op care. As a pet owner, make sure to follow your vet’s advice closely.
Preventing Post-Op Infections in Dogs
A proactive approach during and after surgery is essential to minimizing the risk of infections and ensuring your dog’s recovery is smooth and pain-free.
During Surgery
Preventing post-op infections starts in the operating room with strict sterile techniques. Surgeons carefully sterilize tools and use protective barriers like surgical drapes to reduce contamination. However, bacteria and biofilms can still be a threat, especially in complex procedures.
That's why many surgeons prefer using advanced solutions like Simini Protect Lavage instead of saline or povidone-iodine. Unlike traditional antibiotic solutions, Simini is a non-antibiotic option that effectively reduces biofilms and bacteria better than conventional treatments. This makes it a preferred choice for leading surgeons like Dr. Aldo Vezzoni. With this, vets can significantly lower the risk of post-op infections, improving outcomes for dogs.
After Surgery
After surgery, your role as a pet parent is crucial. Keep the incision site clean and dry, this means no baths until your vet says it’s safe. Use an Elizabethan collar (E-collar) or recovery suit to stop your dog from licking or chewing the wound, as their saliva can introduce harmful bacteria.
Follow your vet’s instructions for giving medications, whether antibiotics to fight infection or anti-inflammatory drugs to reduce swelling. Skipping doses or stopping early can cause problems. Lastly, check the wound daily for redness, swelling, or discharge, and schedule follow-ups as advised. These steps ensure a smooth recovery for your furry friend.
When to Contact Your Veterinarian
It's always better to act quickly if you suspect a post-op infection. Certain signs need immediate attention to prevent complications. Persistent swelling or discharge, especially if it's yellow, green, or has a bad smell, often indicates an infection that needs veterinary care. Similarly, if your dog has a high fever (above 102.5°F), shows a loss of appetite, or seems lethargic, these could be signs of a systemic infection.
A wound that reopens or shows excessive bleeding is also a warning sign and should prompt an urgent visit to the vet. Even if you're unsure whether a symptom is serious, it's always better to call your veterinarian. They can guide you on whether immediate care is necessary or if monitoring at home is enough.
Quick action can make all the difference in your dog's recovery. Remember, your vet is there to help and will always prioritize your dog's well-being.
Conclusion
Proper post-op care is essential for preventing infections and ensuring your dog recovers well. Keeping the surgical site clean and following your vet's instructions are key steps in reducing risks. Spotting symptoms like swelling, discharge, or lethargy early can greatly improve outcomes.
Advanced techniques like Simini Protect Lavage have transformed surgical care by effectively removing bacteria and biofilms, lowering the risk of infection without needing antibiotics. Their use in veterinary practices sets a new standard for safety and success in surgeries.

How Dogs Get Enterococcus faecalis
Learn how dogs acquire Enterococcus faecalis, its transmission routes, risk factors, and prevention methods to protect your pet from infections
What is Enterococcus faecalis?
Enterococcus faecalis is a type of bacteria commonly found in the gastrointestinal tract of dogs. It is a commensal bacterium, meaning it lives with the body’s natural flora without causing harm under normal conditions. In a healthy dog, E. faecalis helps with digestion and maintains a balanced gut microbiome.
However, this bacterium can become opportunistic and pathogenic when a dog’s immune system is weakened or when there is an imbalance in gut bacteria. Factors like prolonged antibiotic use, chronic illness, surgery, or infections can disrupt this balance, allowing E. faecalis to multiply uncontrollably and spread to other tissues. When this occurs, it can lead to urinary tract infections (UTIs), wound infections, or more severe systemic infections.
Although usually harmless, E. faecalis can develop resistance to antibiotics, making infections harder to treat, especially in hospitalized or immunocompromised dogs.
How Do Dogs Get Enterococcus faecalis?
Dogs primarily acquire Enterococcus faecalis from their own gastrointestinal tract, where it naturally exists as part of the normal gut flora. However, under certain conditions, this bacterium can spread and cause infections in other parts of the body.
One of the most common modes of transmission is fecal contamination. If a dog’s feces contain E. faecalis, the bacteria can spread to the urinary tract, wounds, or other vulnerable areas through direct contact. This often happens when a dog grooms itself after defecation or comes into contact with contaminated bedding, floors, or other surfaces.
Environmental exposure is another route of transmission. Dogs can pick up E. faecalis from contaminated water, soil, or surfaces, especially in places like kennels, veterinary clinics, or dog parks. Shared water bowls, medical instruments, and poorly sanitized environments can all serve as sources of bacterial transfer.
Additionally, direct transmission can occur through licking, grooming, or ingesting contaminated food or objects. Dogs frequently use their mouths to explore their surroundings, making it easy for bacteria to spread. Immunocompromised dogs, those recovering from surgery, or those on long-term antibiotics are at a higher risk of developing infections from E. faecalis.
Risk Factors for Enterococcus faecalis Infections in Dogs
Dogs typically carry Enterococcus faecalis in their gastrointestinal tract without issues, but certain factors can increase the risk of this bacterium causing infections, particularly in the urinary tract and other vulnerable areas. These risk factors can be categorized into urinary tract-related factors and systemic conditions that compromise the body's natural defenses.
Urinary Tract-Related Factors
Several conditions affecting the lower urinary tract (LUT) create an environment where E. faecalis can thrive and cause infections:
- Recurrent bacteriuria – Frequent bacterial presence in the urine weakens the urinary tract’s natural defenses, allowing E. faecalis to establish infections.
- Lower urinary tract (LUT) anatomic abnormalities – Structural issues such as congenital defects or acquired conditions (e.g., urethral strictures) can lead to incomplete bladder emptying, increasing bacterial colonization.
- Urolithiasis (bladder stones) – The presence of bladder stones creates a favorable surface for bacterial attachment and biofilm formation, making infections more persistent and harder to treat.
- LUT neoplasia (tumors) – Tumors in the bladder or urethra can cause obstruction, tissue damage, and chronic inflammation, providing an entry point for E. faecalis to invade and multiply.
Systemic Conditions Increasing Risk
Beyond localized urinary tract issues, certain systemic health problems can compromise a dog’s ability to fight off infections:
- Neurologic dysfunction – Conditions affecting nerve control of the bladder (such as intervertebral disc disease or spinal cord injuries) can result in urine retention, which increases bacterial colonization.
- Endocrinopathies (hormonal disorders) – Diseases like diabetes mellitus and hyperadrenocorticism (Cushing’s disease) alter immune function and can lead to sugar-rich urine, which fosters bacterial growth.
- Urinary incontinence – Dogs with incontinence may have prolonged exposure to urine on their skin and mucosa, allowing E. faecalis to migrate from fecal contamination to the urinary tract.
- Corticosteroid administration – Long-term steroid use suppresses the immune system, reducing the body's ability to clear infections effectively.
- Chronic kidney disease (CKD) – Dogs with CKD often have altered urine concentration and immune dysfunction, making them more susceptible to urinary tract infections (UTIs) caused by E. faecalis.
- Urinary catheterization – Catheterized dogs, especially those requiring long-term urinary catheters, face a high risk of bacterial introduction into the bladder, providing E. faecalis a direct pathway to colonize the urinary tract.
Understanding these risk factors is crucial in preventing and managing E. faecalis infections in dogs. Regular veterinary checkups, proper hygiene, and addressing underlying conditions can significantly reduce the likelihood of infection.
Surgical and Post-Operative Infections Due to Enterococcus faecalis
How Surgical Infections Occur
Surgical site infections (SSIs) caused by Enterococcus faecalis can develop when bacteria enter the wound during or after surgery. Several factors contribute to these infections:
- Contaminated surgical tools or implants – If sterilization protocols are inadequate, E. faecalis can be introduced into the surgical site through contaminated instruments, implants, or sutures.
- Poor wound hygiene post-surgery – Inadequate wound care, improper bandage changes, or exposure to dirt and moisture can allow bacteria to multiply and infect the incision site.
- Exposure to multi-drug resistant (MDR) strains in hospital settings – Veterinary hospitals, particularly intensive care units, may harbor antibiotic-resistant E. faecalis strains that can cause difficult-to-treat infections in post-surgical patients.
- Pre-existing conditions like diabetes or immune suppression – Dogs with conditions like diabetes, chronic illness, or those receiving immunosuppressive therapy (e.g., corticosteroids) have a reduced ability to fight infections, increasing their risk.
Common Types of Infections in Post-Surgical Dogs
- Soft tissue infections – E. faecalis can cause swelling, redness, pain, and pus formation at the incision site, potentially leading to abscesses or delayed healing.
- Deep wound infections – When bacteria invade deeper tissues, infections can become more severe, requiring drainage, debridement, or antibiotic therapy.
- Orthopedic infections – Post-surgical infections involving bones, joints, or implants (e.g., TPLO plates) can be particularly challenging to treat, often necessitating prolonged antibiotic use or implant removal.
Preventing E. faecalis infections requires strict surgical asepsis, careful wound management, and appropriate post-operative monitoring to ensure proper healing.
Orthopedic Infections After TPLO Surgery and Enterococcus faecalis
Why TPLO Surgery Is at Risk
Tibial Plateau Leveling Osteotomy (TPLO) is a common surgical procedure for repairing cranial cruciate ligament (CCL) injuries in dogs. However, TPLO surgery carries a risk of post-operative infection, particularly from Enterococcus faecalis, due to several factors:
- Presence of surgical implants – Metal plates and screws used in TPLO surgery provide surfaces where bacteria like E. faecalis can adhere and form protective biofilms, making infections difficult to eliminate.
- Post-surgical inflammation and healing challenges – Normal healing involves inflammation, which can create an environment conducive to bacterial growth if E. faecalis contaminates the surgical site.
Complications Caused by Enterococcus faecalis in TPLO Surgeries
- Biofilm formation on implants – E. faecalis can develop biofilms on metal implants, creating a protective layer that resists antibiotics and the immune system, leading to persistent infections.
- Prolonged healing time – Chronic bacterial presence can delay bone healing, cause ongoing pain, and increase the risk of implant loosening.
- Increased risk of revision surgery or implant removal – If infection persists despite treatment, revision surgery may be necessary to remove infected implants and debride affected tissue, adding to recovery time and cost.
Preventing E. faecalis infections in TPLO cases requires strict aseptic techniques, post-operative monitoring, and early intervention if signs of infection arise.
Preventing Enterococcus faecalis Infections in Dogs
Hygiene Measures
Maintaining proper hygiene is essential in preventing Enterococcus faecalis infections. Cleanliness reduces the risk of bacterial exposure and helps keep your dog healthy:
- Proper cleaning of bedding, bowls, and living areas – Regularly wash your dog’s bedding, food and water bowls, and living spaces to remove bacteria and other contaminants. Disinfecting these items frequently is essential, especially in environments like kennels or vet clinics.
- Regular bathing and grooming – Keeping your dog clean through regular baths and grooming reduces the chance of bacterial buildup on their skin and fur, especially in areas like the paws or genital region, where bacteria can thrive.
Post-Surgery Care
Dogs recovering from surgery are at higher risk for infections like E. faecalis, and proper care can significantly reduce these risks:
- Keeping wounds clean and monitored for signs of infection – Gently clean surgical wounds as recommended by your vet and watch for redness, swelling, or discharge, which could indicate an infection.
- Following veterinary guidelines for post-op wound management – Adhere to all instructions regarding bandage changes, medication, and activity restrictions to promote healing and prevent bacterial contamination.
After surgery, keeping wounds clean and monitored for signs of infection is crucial. During surgery, advanced solutions like Simini Protect Lavage can be used by veterinary surgeons to minimize the risk of infection.
This non-antibiotic surgical lavage solution helps reduce bacterial contamination and prevents biofilm formation on surgical sites.
By using Simini during surgery, the risk of post-surgical infections is significantly lowered, contributing to faster, safer healing
Managing Underlying Health Conditions
Dogs with chronic health conditions are more vulnerable to infections, including E. faecalis:
- Regular vet check-ups for dogs with chronic illnesses – Regular veterinary visits help manage conditions like diabetes or kidney disease, which may predispose dogs to infections.
- Monitoring for early signs of urinary tract or surgical infections – Pay attention to symptoms such as changes in urination, discomfort, or poor wound healing, and seek veterinary care promptly if these signs appear.
By following these preventive measures, you can help protect your dog from E. faecalis infections and promote overall health.

How to Treat MRSP in Dogs: Best Practices
Learn how to treat MRSP in dogs with vet-approved methods. Explore symptoms, best treatments, & prevention tips to manage antibiotic-resistant infections
Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is a bacterial infection in dogs that doesn't respond to many antibiotics. It is related to MRSA (methicillin-resistant Staphylococcus aureus), which affects humans. MRSP often leads to skin infections, ear infections, and, in severe cases, deep tissue infections.
The biggest challenge with MRSP is its antibiotic resistance. Common antibiotics like penicillins and cephalosporins don't work against this bacteria. This resistance happens because of the overuse or misuse of antibiotics, making infections harder to treat. Treatment options are limited to specific, carefully chosen antibiotics or alternative therapies.
Signs Your Dog Might Have MRSP
Dogs with MRSP may show persistent skin infections that do not respond to regular antibiotics. Symptoms include:
- Red, inflamed skin with sores or pustules
- Excessive itching and hair loss
- Recurrent ear infections with discharge
- Slow-healing wounds
- Swelling or pain in the affected area
If your dog shows these signs, a veterinary diagnosis with bacterial culture testing is crucial for proper treatment.
Treatment Options for MRSP in Dogs
Home Care & Infection Control (Immediate Actions)
When dealing with MRSP, preventing the spread of bacteria is just as important as treating the infection. Since MRSP is resistant to many antibiotics, proper hygiene and containment measures can help protect other pets and humans in the household.
- Isolate the infected dog: Keep your dog separated from other pets to prevent bacterial transmission. MRSP can spread through direct contact, shared items, or contaminated surfaces.
- Practice strict hygiene: Always wash your hands thoroughly with soap and water after handling your dog. Use disposable gloves if treating wounds.
- Disinfect frequently used items: Clean bedding, collars, leashes, bowls, and any surfaces your dog touches using pet-safe disinfectants. Wash fabric items in hot water and dry them completely.
- Prevent self-trauma: Dogs with MRSP infections often scratch or lick the affected area, worsening the infection. Use an e-collar (Elizabethan collar) or protective clothing to prevent irritation and reinfection.
Proper infection control begins in the operating room, and if a veterinary surgeon uses an advanced wound irrigation solution like Simini Protect Lavage during surgery, it can help reduce bacterial contamination, including MRSP, lowering the risk of post-operative infections.
Topical Therapy (First-Line Treatment)
Topical therapy is a crucial first step in managing MRSP infections. Since MRSP bacteria live on the skin, direct application of antiseptics and antibiotics can help reduce bacterial load and promote healing.
- Antiseptic baths: Bathe your dog 2–3 times per week using an antiseptic shampoo containing 2–4% chlorhexidine. This helps kill bacteria on the skin and prevent new infections. Allow the shampoo to sit on the coat for 10 minutes before rinsing thoroughly.
- Mupirocin ointment: Apply twice daily to small, localized MRSP lesions. Mupirocin is effective against Staphylococcus pseudintermedius and helps treat infected wounds or hot spots.
- Topical amikacin spray: This antibiotic spray can be used once or twice daily to control bacterial growth in severe or widespread infections. It is often recommended when oral antibiotics are not an option.
Consistency is key—continue treatment for at least 2–4 weeks or as directed by your veterinarian. If symptoms persist or worsen, further medical intervention may be necessary.
Systemic Antibiotic Therapy (For Severe Cases)
Systemic antibiotics should be used only when necessary, as MRSP is resistant to many common antibiotics. Overuse can lead to further resistance, making future infections even harder to treat. In mild cases, topical therapy alone may be enough.
- Culture and sensitivity testing: Before starting any antibiotic, a veterinarian should perform a bacterial culture and sensitivity test. This identifies which antibiotics are effective against the specific MRSP strain in your dog. Treating without testing can lead to failed therapy and stronger resistance.
- Avoid beta-lactam antibiotics: Penicillins and cephalosporins are ineffective against MRSP and should not be used. This includes commonly prescribed antibiotics like amoxicillin-clavulanate or cephalexin.
- Alternative antibiotic options: Depending on test results, chloramphenicol, aminoglycosides (amikacin), clindamycin, or doxycycline may be prescribed. These are not first-line antibiotics and should only be used under veterinary guidance due to possible side effects.
Systemic antibiotic therapy typically lasts 4–6 weeks and requires strict follow-up to monitor effectiveness. If symptoms persist, adjusting the treatment plan may be necessary.
Duration of Treatment (How Long to Continue)
The duration of treatment for MRSP infections depends on the severity and depth of the infection. Stopping treatment too early can lead to recurrence, making the infection harder to eliminate in the future.
- Superficial pyoderma: This is a mild to moderate skin infection affecting the outer layers of the skin. Treatment with topical therapy and, if necessary, systemic antibiotics should continue for at least 3 weeks or one week beyond visible healing.
- Deep pyoderma: If the infection has spread into deeper skin layers, treatment is more intensive. Therapy should last 4–8 weeks or longer, continuing for at least 1–3 weeks after all lesions have healed to prevent relapse.
Why is extended treatment necessary? MRSP is highly resistant, and stopping treatment too soon allows surviving bacteria to multiply, leading to reinfection. This can also make the bacteria more difficult to treat in the future.
Regular veterinary check-ups and follow-up cultures help ensure the infection is fully cleared before stopping treatment.
Supporting Your Dog’s Recovery at Home
Diet & Supplements to Boost Healing
A nutrient-rich diet and targeted supplements can strengthen your dog's immune system and support skin healing after an MRSP infection. Proper nutrition plays a crucial role in reducing inflammation, repairing the skin barrier, and preventing future infections.
- Omega-3 supplements: Fish oil rich in EPA and DHA helps reduce inflammation and promote healthy skin. These essential fatty acids improve the skin barrier, making it more resistant to bacterial infections.
- Probiotics: If your dog has been on antibiotics, adding probiotics helps restore gut balance and support immune function. Look for Lactobacillus and Bifidobacterium strains, which promote good digestion and reduce antibiotic-related side effects.
- Hyaluronic acid sprays: Topical hyaluronic acid (HA) sprays enhance skin hydration and barrier repair, reducing irritation and supporting wound healing. They also help create a protective layer, preventing bacteria from re-entering the skin.
Feeding a high-quality, protein-rich diet with these supplements can help your dog recover faster and build long-term resistance against skin infections. Always consult your veterinarian before adding supplements to your dog’s routine.
Hygiene & Environmental Adjustments
Creating a clean, bacteria-free environment is essential to prevent reinfection and support your dog’s recovery from MRSP. Since MRSP can survive on surfaces, proper hygiene and environmental control help minimize bacterial spread.
- UV sterilization wands: These devices eliminate bacteria, viruses, and fungi on surfaces like bedding, collars, leashes, and food bowls. UV-C light disrupts bacterial DNA, making it an effective chemical-free disinfection method.
- Air purifiers with HEPA filters: MRSP bacteria can spread through air and dust particles. Using an air purifier with a HEPA filter helps capture airborne bacteria and allergens, reducing the risk of reinfection.
- Regular grooming: Keeping your dog’s skin clean is key. Bathe them with antimicrobial shampoos as recommended and brush their coat regularly to remove dirt, dead skin cells, and bacteria. Clean ears, trim nails, and check for any signs of skin irritation.
By maintaining strict hygiene practices and a clean home environment, you can lower bacterial exposure and help your dog heal faster.
Preventing Future MRSP Infections
Preventing reinfection is crucial for dogs that have recovered from MRSP. Since MRSP bacteria can persist in the environment and on the skin, consistent hygiene, early monitoring, and veterinary follow-ups are essential to keep your dog healthy.
- Regular bathing and hygiene: A weekly or biweekly bath with antiseptic shampoos (2–4% chlorhexidine) helps control bacterial levels on the skin. Regular cleaning of bedding, food bowls, and grooming tools prevents contamination.
- Monitoring for early signs: Dogs prone to skin infections should be checked regularly for redness, bumps, hair loss, or excessive scratching. Catching infections early allows for faster treatment with topical antiseptics, reducing the need for systemic antibiotics.
- Routine veterinary checkups: If your dog has a history of MRSP or recurrent skin infections, schedule regular checkups every 3–6 months. Your vet can perform skin cultures or cytology to detect bacteria before a full-blown infection develops.
By staying proactive with hygiene, early intervention, and veterinary care, you can significantly reduce the risk of future MRSP infections and keep your dog’s skin healthy.
When to See a Veterinarian
While home care and prescribed treatments can help manage MRSP infections, some cases require immediate veterinary attention. If your dog’s condition does not improve or worsens, a veterinarian can reassess the treatment plan to prevent complications.
- No improvement after 2 weeks: If your dog is receiving topical or systemic treatment but the infection persists after 2 weeks, it may indicate treatment resistance. A vet may need to adjust the antibiotic plan based on a new culture and sensitivity test.
- Worsening or spreading infection: If redness, swelling, or sores continue to spread despite home care, the infection could be deepening. MRSP can sometimes penetrate deeper tissues, leading to cellulitis or abscess formation, which requires stronger medical intervention.
- Systemic illness signs: If your dog becomes lethargic, refuses food, or develops a fever, the infection may have entered the bloodstream (sepsis) or caused a secondary illness. This is a medical emergency requiring urgent veterinary care.
Early veterinary intervention can prevent severe complications, ensuring a faster and safer recovery for your dog.

MRSP Infection in Dogs: Causes and Symptoms
MRSP infection in dogs is a drug-resistant bacterial infection causing skin issues and wounds. Learn its causes, symptoms, and the best treatment options
What is MRSP Infection in Dogs?
Methicillin-Resistant Staphylococcus pseudintermedius (MRSP) is a type of bacteria that causes infections in dogs and is resistant to many common antibiotics, including methicillin and other beta-lactam antibiotics.
MRSP is a strain of Staphylococcus pseudintermedius, a bacterium naturally found on a dog’s skin and mucous membranes. While regular S. pseudintermedius infections can be treated with standard antibiotics, MRSP infections are much harder to manage due to their resistance to multiple drugs.
Unlike typical bacterial infections, MRSP does not respond to first-line antibiotics, making treatment more complex and prolonged. This resistance develops when bacteria are repeatedly exposed to antibiotics, leading to mutations that allow them to survive even in the presence of these medications.
MRSP is a major concern for veterinarians and dog owners because it can cause persistent skin infections, surgical site infections, and deep tissue infections. These infections are often recurrent and challenging to eradicate.
TL;DR
- MRSP spreads through direct contact, contaminated surfaces, and repeated antibiotic use, making multi-dog environments high-risk.
- Antibiotic resistance makes standard treatments ineffective, leading to persistent and recurrent infections.
- Infected dogs often develop skin lesions, swelling, non-healing wounds, and, in severe cases, fever and lethargy.
- Topical antiseptics and targeted antibiotics may help, but MRSP-related surgical infections remain difficult to manage.
- Simini Protect Lavage is the only effective non-antibiotic solution for MRSP surgical cases, preventing bacterial biofilm formation and reinfection.
How Common is MRSP in Dogs?
MRSP infections are becoming increasingly common in veterinary medicine, with rising cases reported worldwide. While Staphylococcus pseudintermedius is a normal part of a dog’s skin flora, the methicillin-resistant strain (MRSP) has been identified more frequently in veterinary clinics, kennels, and households with multiple pets.
Studies indicate that MRSP prevalence varies by region, but infection rates have increased due to widespread antibiotic use in veterinary medicine. Some research suggests that up to 40% of S. pseudintermedius isolates in certain veterinary hospitals show methicillin resistance.
Where MRSP is Commonly Found
MRSP is often detected in dogs with chronic skin conditions, post-surgical wounds, ear infections, and deep tissue abscesses. It is frequently seen in:
- Dogs with recurrent pyoderma or allergic skin disease
- Postoperative surgical site infections
- Dogs undergoing long-term antibiotic treatment
- Pets in shelters, kennels, or multi-dog households
Why Antibiotic Resistance is Increasing
The overuse and misuse of antibiotics are the primary drivers of MRSP resistance. Repeated exposure to antibiotics, particularly in cases where treatment is stopped early or used unnecessarily, allows bacteria to develop resistance.
Additionally, MRSP can spread between dogs through direct contact or contaminated surfaces, making infection control crucial in veterinary settings.
How Do Dogs Get MRSP?
MRSP is a highly resilient bacterium that spreads easily in veterinary settings and among dogs in close contact. Unlike typical bacterial infections that respond to standard antibiotics, MRSP thrives in environments with frequent antibiotic use, causing treatment-resistant infections.
Ways Dogs Can Contract MRSP
- Direct Contact with Infected Animals - Dogs can contract MRSP by coming into contact with another infected pet. This is especially common in multi-dog households, kennels, and veterinary clinics where animals interact closely.
- Exposure to Contaminated Surfaces - MRSP can survive on objects such as bedding, grooming tools, medical equipment, and kennel surfaces. Dogs that frequently visit grooming facilities, boarding kennels, or veterinary clinics may be exposed to these contaminated environments.
- Repeated Antibiotic Treatments - Overuse or misuse of antibiotics contributes to MRSP infections. When a dog is given antibiotics repeatedly—especially if treatments are stopped early—the bacteria can develop resistance, making future infections harder to treat.
- Weakened Immune System - Dogs with compromised immune systems, whether due to chronic illnesses, endocrine disorders, or stress, are more susceptible to MRSP. Their bodies struggle to fight off infections, increasing the likelihood of colonization by resistant bacteria.
Risk Factors for MRSP Infection
- Dogs with Allergies or Endocrine Disorders - Conditions like atopic dermatitis, hypothyroidism, or Cushing’s disease weaken the skin barrier and immune response, making dogs more vulnerable to MRSP infections.
- Frequent or Prolonged Antibiotic Use - Long-term antibiotic exposure alters bacterial populations, increasing the risk of antibiotic-resistant strains like MRSP.
- Extended Hospital Stays or Frequent Veterinary Visits - Dogs that require hospitalization, surgery, or repeated treatments are at higher risk due to increased exposure to MRSP-contaminated environments.
By understanding these transmission routes and risk factors, veterinarians and pet owners can take preventive measures to reduce the spread of MRSP and protect canine health.
Signs and Symptoms of MRSP in Dogs
MRSP infections primarily affect the skin but can also lead to deeper tissue infections. Since MRSP is resistant to many antibiotics, symptoms often persist despite initial treatments. Recognizing the signs early can help in timely diagnosis and management.
Common Skin-Related Symptoms
MRSP often presents as a skin infection (pyoderma) with visible lesions. You may notice:
- Abscesses or pustules (small pus-filled bumps)
- Redness and inflammation around the affected area
- Crusting or scabbing of the skin
- Non-healing wounds that worsen over time
Hair Loss and Excessive Itching
Dogs with MRSP infections may develop patchy hair loss (alopecia) due to chronic skin irritation. Constant itching, licking, or chewing of the infected area can lead to further skin damage and secondary infections.
Swelling, Pain, or Discomfort
Affected areas may become swollen and tender to the touch. If the infection spreads deeper, pain and localized warmth may be noticeable.
General Signs of Illness
If the infection becomes more severe, dogs may show systemic symptoms, such as:
- Fever
- Lethargy or weakness
- Loss of appetite
Since MRSP infections can mimic other skin conditions, a proper veterinary diagnosis is crucial for effective treatment.
Diagnosis: How Vets Confirm MRSP in Dogs
Diagnosing MRSP requires laboratory testing because it cannot be identified through visual examination alone. Since MRSP is resistant to many antibiotics, early and accurate diagnosis is essential for selecting the right treatment.
Culture and Sensitivity Testing
The most reliable way to confirm MRSP is through bacterial culture and antibiotic sensitivity testing. A veterinarian will collect a sample from an infected area—such as a skin lesion, wound, or ear discharge—using a sterile swab.
This sample is then sent to a laboratory, where technicians grow the bacteria and test its response to various antibiotics. If the bacteria show resistance to methicillin and other common drugs, MRSP is confirmed.
Why MRSP Requires Lab Testing
MRSP infections look similar to other bacterial skin infections, making it impossible to diagnose based on appearance alone. Without lab testing, standard antibiotic treatments may fail, leading to prolonged or worsening infections.
Importance of Early Diagnosis
Timely identification of MRSP allows veterinarians to prescribe the appropriate antibiotic or alternative treatments, reducing the risk of complications. Early diagnosis also helps prevent the spread of MRSP to other pets, especially in multi-dog households, veterinary clinics, and kennels.
How is MRSP Different from Other Staph Infections?
MRSP (Methicillin-Resistant Staphylococcus pseudintermedius) differs from typical Staphylococcus pseudintermedius infections in one key way: antibiotic resistance.
While both types of bacteria can cause skin infections, wounds, and post-surgical complications in dogs, MRSP is resistant to methicillin and many other commonly used antibiotics.
This makes it much harder to treat than regular S. pseudintermedius infections, which typically respond to first-line antibiotics like cephalexin or amoxicillin-clavulanate.
MRSP vs. MRSA: What’s the Difference?
MRSP is often compared to Methicillin-Resistant Staphylococcus aureus (MRSA), another drug-resistant staph infection. However, MRSP primarily affects dogs, while MRSA is more common in humans. Although MRSP can occasionally spread to humans, the risk of transmission is lower compared to MRSA.
Why MRSP is Harder to Treat
- Limited antibiotic options – Many standard antibiotics fail against MRSP, requiring veterinarians to use second-line or specialized treatments.
- Recurrent infections – MRSP infections often return after treatment, requiring long-term management.
- Environmental persistence – MRSP can survive on surfaces like bedding, kennels, and grooming tools, increasing the risk of reinfection.
Because of its resistance and persistence, MRSP requires careful antibiotic selection and strict infection control to prevent outbreaks in veterinary clinics and multi-pet households.
Are Certain Dog Breeds More Prone to MRSP?
Some dog breeds are more susceptible to MRSP due to genetic factors and breed-specific skin conditions. Breeds prone to allergies, skin folds, or chronic dermatitis have a higher risk of developing bacterial infections, which can lead to MRSP if antibiotics are overused.
Breeds at Higher Risk
- Bulldogs, Pugs, and Shar-Peis – Skin folds trap moisture, creating a breeding ground for bacteria.
- Labrador Retrievers and Golden Retrievers – Prone to allergic dermatitis and chronic ear infections.
- German Shepherds – More likely to develop deep pyoderma, a severe skin infection.
Proper skin care and infection prevention are key for these breeds.
Is MRSP Contagious to Other Dogs?
Yes, MRSP can spread between dogs, especially in multi-pet households, kennels, and veterinary clinics. It spreads through direct contact with infected dogs, contaminated surfaces (bedding, food bowls, grooming tools), and shared environments.
Risk Factors for Transmission
- Dogs in kennels, shelters, or veterinary hospitals
- Shared items like toys, blankets, or grooming tools
- Open wounds or skin infections that allow bacteria to enter
Can Asymptomatic Carriers Spread MRSP?
Yes, some dogs carry MRSP without showing symptoms but can spread it to others, making infection control crucial. Regular hygiene and isolation of infected dogs help prevent outbreaks.
Treatment Options for MRSP in Dogs
MRSP infections require a multifaceted treatment approach due to their resistance to common antibiotics. Treatment typically includes culture-guided antibiotic therapy, topical antiseptics, and infection management strategies to prevent recurrence.
Medical Treatments
- Antibiotic Therapy - Since MRSP does not respond to many first-line antibiotics, culture and sensitivity testing is essential to identify effective options. Some MRSP strains remain susceptible to chloramphenicol, doxycycline, rifampin, or amikacin, but each case requires individualized treatment.
- Why Some Antibiotics Don’t Work - MRSP carries resistance genes that make it immune to methicillin and other beta-lactam antibiotics, such as cephalexin and amoxicillin-clavulanate. Using ineffective antibiotics can worsen resistance, leading to chronic or recurrent infections.
Topical Treatments
- Antibacterial Shampoos and Solutions - Regular bathing with chlorhexidine or miconazole-based shampoos helps reduce bacterial load and prevent reinfection.
- Medicated Wipes and Ointments - For localized infections, antiseptic wipes, gels, or ointments (containing chlorhexidine or mupirocin) help control bacterial spread and promote healing.
The Role of Simini in Surgical MRSP Cases
For MRSP-related post-surgical infections, Simini Protect Lavage is a critical non-antibiotic solution. MRSP increases the risk of surgical site infections (SSIs), which can be difficult to treat with standard antibiotics.
Simini Protect Lavage effectively removes bacteria, disrupts biofilms, and lowers infection risks without contributing to antibiotic resistance. It is particularly beneficial for orthopedic surgeries, wound management, and post-operative care, where MRSP contamination poses a significant challenge.
For non-surgical MRSP infections, a combination of targeted antibiotics, antiseptic treatments, and strict hygiene measures is necessary to prevent recurrence and transmission.
Managing MRSP at Home: Infection Control and Prevention
MRSP can spread easily in multi-pet households, making strict hygiene and infection control measures essential. Since MRSP is resistant to many antibiotics, preventing transmission is just as important as treating the infected dog.
Strict Hygiene Measures
- Wash hands thoroughly after handling an infected dog, especially before touching other pets or household items.
- Use disposable gloves when applying topical treatments to avoid spreading bacteria.
- Limit direct contact, such as cuddling or allowing the dog to sleep on furniture, to prevent contamination.
Cleaning and Disinfecting
- Wash bedding, toys, collars, and bowls frequently using hot water and pet-safe disinfectants.
- Clean surfaces like floors and furniture with antibacterial solutions to eliminate lingering bacteria.
- Use separate grooming tools and feeding dishes for the infected dog to prevent cross-contamination.
Minimizing Spread to Other Pets and Humans
- Keep the infected dog in a separate space until the infection resolves.
- Regularly bathe pets with antibacterial shampoos if they share a home with an infected dog.
- Although MRSP is rarely transmitted to humans, immunocompromised individuals should take extra precautions when handling an infected pet.
Consistent infection control measures help prevent MRSP from spreading and reduce the risk of reinfection.
How to Prevent MRSP in Dogs
Preventing MRSP infections requires a proactive approach that focuses on responsible antibiotic use, regular veterinary care, and maintaining a strong immune system.
Since MRSP thrives in environments where antibiotics are overused or misused, reducing unnecessary antibiotic exposure is key to controlling its spread.
Responsible Antibiotic Use to Prevent Resistance
One of the biggest contributors to MRSP infections is antibiotic resistance, which develops when antibiotics are used improperly. To prevent this:
- Always complete prescribed antibiotic courses, even if symptoms improve before finishing the medication.
- Avoid using antibiotics without veterinary guidance, as incorrect treatment can promote resistant bacteria.
- If your dog has a history of bacterial infections, ask your vet about alternative treatments, such as antibacterial shampoos or topical antiseptics, instead of relying on systemic antibiotics.
Regular Vet Check-Ups to Detect Early Signs
Routine veterinary visits help catch skin infections, wounds, or other risk factors before they become severe. Early intervention reduces the chance of an infection becoming resistant to treatment.
Dogs with allergies, endocrine disorders, or chronic skin issues should have frequent skin assessments to monitor for signs of bacterial infections.
Strengthening the Immune System Through Diet and Hygiene
A strong immune system helps dogs fight off bacterial infections naturally. To improve immunity:
- Feed a balanced diet with high-quality proteins, essential fatty acids, and vitamins. Omega-3 and Omega-6 fatty acids support skin health, reducing infection risk.
- Maintain good hygiene by regularly bathing dogs with veterinary-approved shampoos to remove bacteria from the skin.
- Keep bedding, grooming tools, and food bowls clean to prevent bacterial buildup.
Prognosis: Can Dogs Recover from MRSP?
How Long It Takes to Treat MRSP
The duration of MRSP treatment depends on the severity of the infection and the effectiveness of treatment.
- Mild skin infections may resolve within 4-6 weeks with proper antibiotic and topical therapy.
- Deep or recurrent infections can take several months to fully heal, requiring a combination of antibiotics, antiseptic treatments, and strict hygiene measures.
- Post-surgical MRSP infections require specialized wound management, and in severe cases, additional procedures may be needed to remove infected tissue.
Chances of Recurrence and Long-Term Management
MRSP has a high recurrence rate, especially in dogs with underlying conditions like allergies, hypothyroidism, or chronic skin disease. Preventing reinfection requires:
- Monitoring for early signs of reinfection, such as skin redness, pustules, or excessive itching.
- Following hygiene protocols to minimize bacterial spread in the home.
- Using non-antibiotic alternatives like antiseptic washes and medicated shampoos to reduce bacterial load without contributing to antibiotic resistance.
When to Seek Veterinary Care for Persistent Infections
If a dog’s MRSP infection does not improve with treatment, spreads to deeper tissues, or recurs frequently, veterinary intervention is crucial. Seek immediate care if:
- Lesions worsen or new infections appear despite antibiotic therapy.
- The dog develops fever, lethargy, or loss of appetite, which may indicate a systemic infection.
- A post-surgical wound shows signs of MRSP, as these infections require specialized management to prevent complications.
With early detection, responsible treatment, and infection control, dogs with MRSP can recover and live healthy lives while minimizing the risk of recurrence.

The first step in wound care is to assess the severity of the injury. It's important to determine if the wound is minor or if it needs immediate veterinary attention.
- Assessing Wound Severity
- Look for deep punctures, cuts, or heavy bleeding.
- Check if any foreign object, such as a thorn or glass, is stuck in the wound.
- Notice signs of severe pain, limping, or visible bone or muscle tissue.
- When to Seek Veterinary Attention
- Excessive bleeding that doesn’t stop after applying gentle pressure for 5-10 minutes.
- Deep wounds or punctures, especially those from bites.
- Wounds near the eyes, ears, or sensitive areas.
- Signs of infection like redness, swelling, or pus.
- Prepare a Clean Environment
- Wash your hands thoroughly or wear disposable gloves.
- Place your dog in a calm, well-lit area to reduce stress and movement.
- Use a clean surface or towel for your dog to lie on during treatment.
B. Cleaning the Wound
Proper cleaning is essential to remove bacteria and debris from the wound without causing more irritation.
- Use Safe Solutions
- Saline solution (homemade: 1 teaspoon of salt in 1 liter of boiled water, cooled).
- 2% chlorhexidine or diluted povidone-iodine (mixed to a weak tea-like color). These can be purchased from veterinary clinics or pharmacies if recommended by your vet.
- Do Not Use alcohol, hydrogen peroxide, or strong antiseptics as they can damage healthy tissue.
- Cleaning Steps
- Gently flush the wound with saline or antiseptic solution using a syringe or spray bottle.
- Remove dirt or debris with sterile gauze or tweezers disinfected with alcohol.
- Pat the wound dry with a clean, sterile cloth to prevent moisture that encourages bacterial growth.
- Do’s and Don’ts
- Do: be gentle and keep your dog calm to prevent sudden movements.
- Don’t: scrub the wound harshly or use dirty materials, as this can increase the risk of infection.
C. Applying Antimicrobial Ointments
Antimicrobial ointments stop bacteria from growing and help wounds heal faster.
- Choose Pet-Safe Ointments
- Veterinary-approved products, like those containing silver sulfadiazine or mupirocin, are commonly used for wound care in dogs. Always make sure that any product you use is safe for pets.
- Check with your vet before using over-the-counter creams.
- Why Human Ointments Are Unsuitable
- Many have ingredients that are toxic to dogs if swallowed, like zinc or certain pain-relief agents.
- They might not be suitable for sensitive dog skin.
- Application Tips
- Apply a thin, even layer to the wound after cleaning.
- Don't use too much ointment, as thick layers can trap moisture and slow down healing.
D. Bandaging the Wound
Bandaging protects the wound from dirt, bacteria, and your dog's natural tendency to lick or scratch.
- Steps for Bandaging
- Place a sterile, non-stick gauze pad over the wound.
- Wrap a soft, self-adhesive bandage around the gauze, making sure it's snug but not too tight.
- Leave enough space for two fingers to slide under the bandage to ensure proper circulation.
- Tips for Proper Bandaging
- Avoid wrapping too tightly, as this can cut off blood flow.
- Use waterproof coverings if the wound is in a spot that might get wet, like the paw.
- Check for swelling or discoloration, which means the bandage is too tight.
E. Preventing Licking or Scratching
Dogs naturally lick their wounds, which can introduce harmful bacteria and slow down healing.
- Use Protective Gear
- Elizabethan Collars (E-Collars): Traditional plastic cones work well but may be uncomfortable.
- Soft or Inflatable Collars: These options are more comfortable and still prevent access to the wound.
- Protective Wraps: For areas like the legs, consider specially designed covers.
- Risks of Licking
- Saliva has bacteria that can easily infect open wounds.

Post-Operative Infection in Dogs: Symptoms and Solutions
Learn about symptoms and solutions for post-operative infections in dogs to ensure a smooth and healthy recovery after surgery
Surgical procedures can save a dog's life or improve their quality of life, but recovery is just as important. Post-operative infections are among the most common complications after surgery in dogs. These infections can slow healing, cause discomfort, and in severe cases, pose serious risks to your pet's health. Knowing how infections occur, what signs to look for, and how to prevent them can greatly improve your dog's recovery.
As someone who has performed many surgeries, We want to share what you need to know to ensure a smooth and infection-free healing process. Let's understand how to care for your dog after surgery and prevent complications.
What Are Post-Op Infections in Dogs?
Post-op infections in dogs happen when bacteria enter a surgical wound, causing inflammation, delayed healing, and discomfort. These infections usually occur due to contamination during surgery, poor wound care, or a weakened immune system. Common bacteria involved include Staphylococcus, Pseudomonas, and Escherichia coli.
Factors like poor hygiene, excessive licking of the wound, or exposure to dirty environments increase the risk. Dogs with conditions like diabetes or obesity are more at risk because their immune systems may not fight infections well.
Statistics show that post-op infections in dogs occur in about 2% to 5% of surgical cases, depending on the type and length of the procedure. For more complex surgeries, like orthopedic or implant-based operations, the infection rate can rise to 8% or more.
Understanding these causes and risks is crucial for ensuring a smooth recovery for your dog after surgery.
Signs of Post-Op Infections in Dogs
Recognizing the signs of a post-op infection early can prevent complications and help your dog recover smoothly. Here are the symptoms to watch for:
- Redness, swelling, or warmth at the incision site: While mild redness is normal after surgery, excessive redness, noticeable swelling, or warmth around the wound may indicate an infection. This is often related to inflammation in the area.
- Pain, lethargy, or loss of appetite: If your dog seems unusually tired, uninterested in food, or shows signs of discomfort when the incision is touched, it could mean the wound is infected. Pain may result from tissue inflammation or an underlying abscess.
- Foul odor or discharge from the wound: Pus-like discharge—yellow, green, or bloody—and a bad smell are strong signs of a bacterial infection.
- Fever or abnormal behavior: A body temperature above 102.5°F, along with shivering, hiding, or restlessness, may indicate a systemic infection.
If you notice any of these symptoms, consult your vet promptly. Early treatment is crucial for your dog’s health and comfort.
Risk Factors That Increase the Chances of Infection
Certain factors make some dogs more likely to get post-op infections. Knowing these risks can help you take preventive steps.
- Pre-existing conditions: Dogs with diabetes, obesity, or diseases that weaken the immune system are at higher risk. These conditions slow wound healing and make it harder for the body to fight bacteria. For example, in diabetic dogs, high blood sugar can encourage bacterial growth, increasing the risk of infection.
- Longer surgery times: Longer surgeries give bacteria more time to enter the wound. Also, extended anesthesia can weaken the immune response, making the dog more vulnerable. Surgeons try to keep surgery times short while being precise to reduce this risk.
- Use of urinary catheters or preoperative shaving techniques: Catheters can introduce bacteria into the urinary tract if not handled correctly. Similarly, shaving the surgical site can cause tiny cuts, allowing bacteria to enter. Proper surgical protocols, like using clippers instead of razors and keeping a sterile environment, greatly reduce these risks.
Many of these factors can be managed with careful preparation and diligent post-op care. As a pet owner, make sure to follow your vet’s advice closely.
Preventing Post-Op Infections in Dogs
A proactive approach during and after surgery is essential to minimizing the risk of infections and ensuring your dog’s recovery is smooth and pain-free.
During Surgery
Preventing post-op infections starts in the operating room with strict sterile techniques. Surgeons carefully sterilize tools and use protective barriers like surgical drapes to reduce contamination. However, bacteria and biofilms can still be a threat, especially in complex procedures.
That's why many surgeons prefer using advanced solutions like Simini Protect Lavage instead of saline or povidone-iodine. Unlike traditional antibiotic solutions, Simini is a non-antibiotic option that effectively reduces biofilms and bacteria better than conventional treatments. This makes it a preferred choice for leading surgeons like Dr. Aldo Vezzoni. With this, vets can significantly lower the risk of post-op infections, improving outcomes for dogs.
After Surgery
After surgery, your role as a pet parent is crucial. Keep the incision site clean and dry, this means no baths until your vet says it’s safe. Use an Elizabethan collar (E-collar) or recovery suit to stop your dog from licking or chewing the wound, as their saliva can introduce harmful bacteria.
Follow your vet’s instructions for giving medications, whether antibiotics to fight infection or anti-inflammatory drugs to reduce swelling. Skipping doses or stopping early can cause problems. Lastly, check the wound daily for redness, swelling, or discharge, and schedule follow-ups as advised. These steps ensure a smooth recovery for your furry friend.
When to Contact Your Veterinarian
It's always better to act quickly if you suspect a post-op infection. Certain signs need immediate attention to prevent complications. Persistent swelling or discharge, especially if it's yellow, green, or has a bad smell, often indicates an infection that needs veterinary care. Similarly, if your dog has a high fever (above 102.5°F), shows a loss of appetite, or seems lethargic, these could be signs of a systemic infection.
A wound that reopens or shows excessive bleeding is also a warning sign and should prompt an urgent visit to the vet. Even if you're unsure whether a symptom is serious, it's always better to call your veterinarian. They can guide you on whether immediate care is necessary or if monitoring at home is enough.
Quick action can make all the difference in your dog's recovery. Remember, your vet is there to help and will always prioritize your dog's well-being.
Conclusion
Proper post-op care is essential for preventing infections and ensuring your dog recovers well. Keeping the surgical site clean and following your vet's instructions are key steps in reducing risks. Spotting symptoms like swelling, discharge, or lethargy early can greatly improve outcomes.
Advanced techniques like Simini Protect Lavage have transformed surgical care by effectively removing bacteria and biofilms, lowering the risk of infection without needing antibiotics. Their use in veterinary practices sets a new standard for safety and success in surgeries.
As a pet owner, always consult your veterinarian for advice and follow their recommendations closely. Your attention and commitment are vital to your dog's health and happiness.
