Understanding Staph Infections in Dogs
Staph infections are the most commonly seen bacterial skin problems in dogs, caused by the overgrowth of Staphylococcus bacteria on the surface of a dog’s skin (American Kennel Club). Staphylococcus pseudintermedius is the particular strain of bacteria that is often associated with these infections. While these bacteria typically live harmlessly in a dog’s mucous membranes, they can cause infections when the bacteria are no longer in harmony on the skin.
Causes of Staph Infections
Staph infections in dogs occur when there is an overgrowth of Staphylococcus bacteria on the surface of the skin. This overgrowth can happen when the skin barrier becomes damaged or compromised, allowing the bacteria to multiply (PetMD). Common causes of staph infections in dogs include:
- Skin injuries or wounds that provide an entry point for bacteria.
- Allergies, which can lead to skin inflammation and make the skin more susceptible to infection.
- Weakened immune system, either due to certain medications or underlying health conditions.
- Flea infestations or other parasitic infections that irritate the skin.
- Hormonal imbalances that affect the health of the skin.
Common Symptoms to Watch For
Recognizing the symptoms of a staph infection in your dog is important for early detection and proper treatment. The symptoms can vary depending on the severity and location of the infection. Common symptoms of staph infections in dogs include:
- Redness and inflammation of the skin.
- Itchiness and scratching.
- Hair loss or thinning.
- Crusting or scabbing of the skin.
- Moist or oozing skin.
- Skin sensitivity or tenderness.
- Skin rash or hives.
In more severe cases or deep staph infections, additional symptoms may include:
- Fever.
- Lethargy or decreased energy.
- Shivering or trembling.
- Decreased appetite.
- Draining tracts or abscesses.
If you notice any of these symptoms in your dog, it’s important to consult with a veterinarian for proper diagnosis and treatment. Early intervention can help prevent the infection from spreading and minimize discomfort for your dog.

Understanding the causes and symptoms of staph infections in dogs is the first step in effectively managing and treating these infections. In the next sections, we will explore factors that increase susceptibility to staph infections, the diagnostic methods used by veterinarians, treatment options, and preventative measures to minimize the risk of recurring or resistant infections.
Factors Increasing Susceptibility
Allergies and Weakened Immune Systems
Dogs with allergies or weakened immune systems are more susceptible to staph infections in dogs. Staph infections can occur in various parts of the body, such as the skin, ears, respiratory, reproductive, or urinary tracts. They can also develop after surgical procedures, especially if the immune system is compromised (American Kennel Club).
Puppies and adult dogs with chronic illnesses are particularly vulnerable to staph infections due to their weakened immune systems. Dogs with pre-existing conditions like environmental allergies, food allergies, hypothyroidism, or ectoparasites are also more prone to staph infections (PetMD). Diseases like atopic dermatitis and allergies can cause the skin to become inflamed and itchy, breaking down the skin barrier and allowing bacteria to penetrate and cause an infection. Although antibiotics can clear the infection, if the underlying inflammation is not controlled, it is likely that the staph bacteria will cause another infection in the future (Pet Dermatology Clinic).
Certain diseases, such as hypothyroidism or Cushing’s syndrome, can weaken the immune system and make dogs more prone to staph infections. Compromises in the skin barrier and immune system allow pathogens to invade the body and multiply, leading to infections in various parts of the body (American Kennel Club).
Breeds Prone to Staph Infections
While staph infections can affect any breed of dog, some breeds are more prone to these infections. Breeds like Pugs, English Bulldogs, Mastiffs, French Bulldogs, and Shar-Peis have a higher susceptibility to staph infections. Additionally, breeds that are prone to environmental allergies, such as Pit Bull Terriers, Golden Retrievers, and Cocker Spaniels, are also more vulnerable to these infections. Dogs with compromised immune systems due to age or underlying medical conditions are at an increased risk as well.
It’s important for dog owners to be aware of their pet’s susceptibility to staph infections, especially if they have allergies or weakened immune systems. Monitoring for symptoms and taking appropriate preventive measures can help minimize the chances of staph infections and promote the overall health and well-being of your furry friend.
Diagnosing Staph Infections in Dogs
To accurately diagnose a staph infection in dogs, veterinarians employ several diagnostic methods. These include skin cytology examination and aerobic skin culture and sensitivity testing.
Skin Cytology Examination
Skin cytology is a common diagnostic procedure used to identify staph infections in dogs. During this examination, a small sample is taken from the affected area of the dog’s skin. This sample is typically collected by placing a piece of clear tape on the lesion and then examining it under a microscope. The goal of this test is to identify the presence of round-shaped bacteria called cocci, which are indicative of a staph infection.
By analyzing the sample, veterinarians can determine the type and severity of the staph infection. This information helps guide the appropriate treatment plan for the dog.
Aerobic Skin Culture and Sensitivity Testing
In addition to skin cytology, veterinarians may also conduct aerobic skin culture and sensitivity testing to further diagnose a staph infection in dogs. This test involves collecting a sample from the affected area and sending it to a laboratory for analysis.
During the test, the sample is cultured in a controlled environment to encourage the growth of bacteria. This allows the identification of the specific strain of bacteria causing the infection. Furthermore, sensitivity testing is performed to determine which antibiotics are effective against the bacteria strain. This step is crucial as it helps veterinarians prescribe the most appropriate antibiotic treatment, especially considering the rising prevalence of antibiotic-resistant staph infections in dogs (PetMD).
By combining the results of skin cytology and aerobic skin culture and sensitivity testing, veterinarians can accurately diagnose staph infections in dogs and develop a targeted treatment plan to combat the infection. It’s important to consult a veterinarian if you suspect your dog may have a staph infection, as they can provide a proper diagnosis and recommend the most appropriate treatment options.
Treatment Options for Staph Infections
When it comes to treating staph infections in dogs, there are various options available to alleviate the symptoms and eliminate the infection. The treatment approach depends on the severity of the infection and may involve a combination of topical solutions and medications, as well as systemic antibiotics.
Topical Solutions and Medications
For milder cases of staph infections in dogs, topical therapy is often the first line of treatment. This involves using medicated shampoos, sprays, ointments, wipes, and mousse specifically formulated to combat bacterial infections. These topical solutions contain antibacterial agents that help eliminate the staph bacteria from the skin.
Medicated shampoos are particularly effective in treating staph infections on the skin. They are designed to cleanse the affected areas and provide relief from itching and inflammation. Additionally, wipes, ointments, and sprays can be used to target specific areas or provide continuous antibacterial protection.
It’s important to follow the instructions provided by your veterinarian or the product manufacturer when using topical solutions. Consistency and thoroughness in application are key to achieving the desired results. Keep in mind that some dogs may require sedation or assistance during bathing or application to ensure proper coverage.
Systemic Antibiotics and Their Importance
In more severe cases or when the infection has spread beyond the skin, systemic antibiotics may be necessary to combat the staph infection. These antibiotics are administered orally or through injection and work internally to eliminate the bacteria from the body.
Common antibiotics prescribed for staph infections in dogs include cephalexin, cefpodoxime, and clindamycin. It’s important to complete the full course of treatment as prescribed by your veterinarian, even if the symptoms improve before the antibiotics are finished. This helps prevent antibiotic resistance and recurrence of the infection.
In some cases, the itching and discomfort associated with staph infections may be managed with medications such as Apoquel® or Cytopoint® to provide relief for your dog while addressing the underlying infection. Always consult with your veterinarian to determine the most appropriate treatment plan for your dog’s specific condition.
Remember, the treatment of staph infections in dogs should be supervised and guided by a veterinarian. They can provide a proper diagnosis, recommend the most effective treatment options, and monitor your dog’s progress. It’s essential to maintain good hygiene practices, keep your dog’s skin clean and dry, and address any underlying issues that may contribute to the infection.
By following the prescribed treatment plan and working closely with your veterinarian, you can help your dog recover from a staph infection and ensure their overall health and well-being.
Recurring Staph Infections in Dogs
While treatment can effectively resolve staph infections in dogs, some dogs may experience recurring infections, even after treatment. Addressing the underlying causes and managing allergic reactions are key aspects of managing recurring staph infections.
Addressing Allergic Reactions
In some cases, dogs can develop allergies to Staphylococcal bacteria, which can contribute to recurring infections. Allergic reactions occur when the immune system overreacts to the presence of these bacteria, leading to inflammation and skin irritation. Identifying and addressing these allergic reactions is crucial in managing recurring staph infections.
To determine the specific allergens causing the reaction, your veterinarian may recommend allergy testing. Once the allergens are identified, avoidance strategies can be implemented. This may involve making dietary changes, using hypoallergenic grooming products, or reducing exposure to environmental allergens.
Long-Term Desensitization Therapy
Long-term desensitization therapy, also known as allergy shots, can be an effective treatment option for staphylococcal hypersensitivity in dogs. This therapy aims to retrain the immune system and reduce hypersensitivity reactions to Staphylococcal bacteria.
Desensitization therapy involves administering routine small-dose injections of staphylococcal bacterin over an extended period. According to the American Kennel Club, this treatment can help reprogram the immune system and prevent allergic reactions. Most dogs will require routine injections for the first one to two years, followed by attempts to reduce the frequency of injections.
Desensitization therapy is successful in up to 77% of cases, as mentioned by VCA Hospitals. It can lead to significant improvement when other treatments have failed. After an initial series of daily injections, subsequent injections are administered subcutaneously at intervals ranging from every three to four days to every two weeks.
In cases where desensitization therapy is not successful, periodic treatment with antibiotics and medicated baths may be necessary to control recurring staph infections.
By addressing allergic reactions and considering long-term desensitization therapy, dog owners can take proactive steps to manage and reduce the occurrence of recurrent staph infections in their furry friends. It’s important to work closely with a veterinarian to develop a comprehensive treatment plan tailored to the specific needs of the dog.
Managing Resistant Staph Infections
When it comes to managing staph infections in dogs, it’s important to address the challenges posed by methicillin resistance. Methicillin-resistant staphylococci have acquired resistance to certain antibiotics, making treatment more challenging and expensive. Here, we will explore the concerns associated with methicillin resistance and the importance of proper grooming practices in managing resistant staph infections in dogs.
Concerns with Methicillin Resistance
Methicillin resistance in staphylococci is primarily associated with the acquisition of a gene called mecA, which becomes part of the bacterial genome and is passed on to daughter cells (Today’s Veterinary Practice). This resistance complicates the treatment of staph infections, as the bacteria become less susceptible to certain antibiotics commonly used for treatment. It is important to note that methicillin-resistant staph infections in dogs are primarily caused by Staphylococcus pseudintermedius, a major pathogen in canine pyoderma. Although Staphylococcus aureus, a human pathogen, has been identified in dogs, its methicillin resistance raises concerns about potential zoonotic transmission (Today’s Veterinary Practice).
To effectively manage methicillin-resistant staph infections, proper diagnosis through culture and sensitivity testing is crucial. This helps identify the specific bacteria causing the infection and determine the most effective antibiotics for treatment. Your veterinarian will guide you in selecting appropriate antibiotics based on the sensitivity results.
Proper Grooming Practices
Proper grooming practices play a vital role in managing resistant staph infections in dogs. If your dog is diagnosed with an antibiotic-resistant staph infection, it is important to inform your groomer in advance so that additional precautions can be taken. In some cases, it may be necessary to delay grooming until the infections have cleared (Pet Dermatology Clinic). This helps prevent the spread of bacteria to other dogs and reduces the risk of reinfection.
Regular bathing and hygiene practices are essential in managing staph infections. Use medicated shampoos or topicals recommended by your veterinarian to help control the infection and soothe your dog’s skin. Follow your veterinarian’s instructions regarding frequency and duration of bathing.
Additionally, maintaining a clean environment for your dog is crucial. Wash your dog’s bedding regularly, vacuum frequently to remove any potential sources of bacteria, and disinfect surfaces to minimize the risk of reinfection.
By addressing the concerns associated with methicillin resistance and implementing proper grooming practices, you can effectively manage resistant staph infections in dogs. Remember to work closely with your veterinarian to develop a comprehensive treatment plan that includes appropriate antibiotics, topicals, and hygiene practices. With diligent care and attention, you can help alleviate your dog’s discomfort and promote the healing of their skin.
