Understanding Staph Infections
Staph infections in dogs are a common skin condition caused by the overgrowth of Staphylococcus bacteria on the surface of the dog’s skin. These infections typically occur when the skin barrier is damaged or the immune system is weakened. Understanding the causes and symptoms of staph infections is crucial for timely identification and appropriate treatment.
Causes of Staph Infections
The primary cause of staph infections in dogs is the proliferation of Staphylococcus bacteria on the skin. This overgrowth can be triggered by various factors, including:
- Skin barrier damage: Any break in the dog’s skin, such as a cut, wound, or scratch, can create an entry point for Staphylococcus bacteria to invade and cause an infection.
- Weakened immune system: Dogs with weakened immune systems, either due to underlying health conditions or certain medications, are more susceptible to staph infections.
Symptoms of Staph Infections
Staph infections in dogs can present with a range of symptoms, depending on the severity and location of the infection. Common signs of staph infections include:
- Inflammation around wounds: If a staph infection occurs near a wound, there may be redness, swelling, and tenderness in the area.
- Itchiness and skin lesions: Dogs with staph infections often experience intense itching, which can lead to scratching and the formation of skin lesions.
- Hair loss: Staph infections can cause hair loss or thinning in the affected areas.
- Fever and loss of appetite: In more severe cases, dogs may exhibit symptoms such as fever, reduced appetite, and lethargy.
- Respiratory symptoms: In rare instances, staph infections can affect the respiratory system, resulting in symptoms like coughing, labored breathing, and nasal discharge.
- Urinary symptoms: Deep staph infections can sometimes lead to urinary tract symptoms such as straining or frequent urination.
It’s important to note that staph infections can manifest differently depending on whether they are superficial or deep. Superficial infections primarily affect the skin and are characterized by symptoms like rash, itchiness, hair loss, redness, crusting, and moist skin. On the other hand, deep staph infections penetrate deeper layers of tissue and can cause additional symptoms such as fever, skin sensitivity, lethargy, shivering, decreased appetite, and draining tracts.
If you suspect that your dog may have a staph infection, it is recommended to consult with a veterinarian for a proper diagnosis and appropriate treatment. Early detection and intervention can help prevent the infection from worsening and promote a speedy recovery.

Vulnerable Dogs
Staph infections can affect dogs of all ages and breeds. However, certain factors can increase a dog’s risk of developing a staph infection, and certain breeds may be more prone to these infections.
Factors Increasing Risk
Dogs with allergies or diseases that weaken the immune system, such as hypothyroidism or Cushing’s syndrome, are more prone to staph infections. These conditions compromise the dog’s skin barrier and immune system, allowing pathogens to invade the body and multiply, leading to infections in various parts of the body (American Kennel Club). Puppies and adult dogs with chronic illnesses are also more susceptible to staph infections due to weakened immune systems. Additionally, dogs with pre-existing conditions affecting the skin barrier, such as environmental allergies, food allergies, hypothyroidism, or ectoparasites, are at a higher risk of staph infections (PetMD).
Breeds Prone to Infections
Certain dog breeds are more vulnerable to staph infections. Breeds with skin folds on their face or body, such as Pugs, English Bulldogs, Mastiffs, French Bulldogs, and Shar-Pei, have an increased risk of developing staph infections. The skin folds can create a warm and moist environment that promotes bacterial growth and colonization. Breeds prone to environmental allergies, such as Pit Bull Terriers, French Bulldogs, and Golden Retrievers, are also at a higher risk of staph infections (PetMD).
It’s important for dog owners to be aware of these factors and closely monitor their furry companions for any signs of a staph infection. If you suspect your dog may have a staph infection, consult with a veterinarian for an accurate diagnosis and appropriate treatment.

Diagnosis and Treatment
When it comes to staph infection in dogs, timely diagnosis and appropriate treatment are crucial for your furry friend’s health and well-being. Veterinary professionals employ various diagnostic procedures to confirm the presence of a staph infection, followed by tailored treatment options.
Diagnostic Procedures
To diagnose a staph infection in dogs, veterinarians may utilize different diagnostic procedures, depending on the severity and location of the infection. Two commonly employed methods are:
-
Skin Cytology: In this procedure, a sample of the affected skin is collected and examined under a microscope. The presence of round-shaped bacteria called cocci can indicate a staph infection (PetMD).
-
Aerobic Skin Culture and Sensitivity: This gold standard test involves collecting a sample and conducting a laboratory analysis to identify the specific strain of bacteria causing the infection. Additionally, the test determines the bacteria’s resistance to antibiotics, aiding in the selection of appropriate treatment.
Treatment Options
The treatment for staph infections in dogs may vary based on the severity of the infection and the individual dog’s needs. Treatment options include:
-
Topical Therapies: For mild cases or localized infections, veterinarians may recommend topical treatments. These can include medicated antibacterial shampoos, wipes, mousse, ointments, and sprays. These topical therapies help reduce the bacterial load on the skin and promote healing.
-
Systemic Antibiotics: In more severe cases or when topical treatments are ineffective, systemic antibiotics may be necessary. Oral antibiotics, such as cephalexin, cefpodoxime, or clindamycin, may be prescribed. These medications work to eliminate the infection from within the body, aiding in a full recovery.
-
Addressing Itchiness: It is essential to address any itchiness associated with the staph infection. Veterinarians may recommend appropriate treatments like Apoquel® or Cytopoint® to alleviate discomfort and prevent further complications.
Treatment plans may be customized based on the specific needs of your dog and the severity of the infection. It is important to diligently follow the prescribed treatment and complete the full course of medication, even if symptoms improve. Regular follow-up appointments with your veterinarian will ensure that the infection is properly managed and monitored for a successful recovery.
By promptly diagnosing a staph infection through diagnostic procedures and administering the appropriate treatment, you can help your dog overcome the infection and restore their skin health. Remember to consult with your veterinarian for personalized guidance and adhere to their recommendations for the best possible outcome.
Contagion Concerns
When it comes to staph infections in dogs, one common concern for dog owners is whether these infections can be transmitted to humans. In this section, we will address the potential for human-to-dog transmission of staph infections and discuss preventive measures to minimize the risk.
Human to Dog Transmission
Research has shown that there is a possibility of transmission of Staphylococcus aureus (S. aureus) between humans and dogs. A study conducted on households with dogs found that 36.9% of humans and 5.4% of dogs carried S. aureus. However, the transmission rate from humans to dogs was lower compared to human-to-human transmission rates. In households where humans were carriers of S. aureus, the transmission rate to dogs was 19.0%, while the human-to-human transmission rate was 29.0% (NCBI).
It’s important to note that methicillin-resistant S. aureus (MRSA) was not detected in dogs during the study. MRSA is a strain of S. aureus that is resistant to certain antibiotics and is of particular concern in human healthcare settings. However, transmission of MRSA from humans to dogs is considered unlikely based on current research.
Another species of Staphylococcus that can be found in dogs is Staphylococcus pseudintermedius (S. pseudintermedius). This species is primarily associated with infections in dogs and is less commonly found in humans. Research has shown that there can be instances of transmission between dogs and humans living in the same household. In one study, S. pseudintermedius was isolated from 37.5% of dogs in households but only from 0.6% of humans. Whole-genome sequencing indicated relatedness between isolates found in humans and dogs from the same household (NCBI).
Preventive Measures
To minimize the risk of transmission of staph infections between dogs and humans, it’s important to take certain preventive measures:
-
Good hygiene practices: Regular handwashing with soap and water before and after handling your dog can help reduce the risk of transmission. Avoid close contact with your dog’s wounds or sores, and if you do come into contact with them, wash your hands thoroughly.
-
Proper wound care: If your dog has a staph infection, ensure that you follow the veterinarian’s instructions for wound care. Keeping the infected area clean and protected can help prevent the spread of infection.
-
Avoid sharing personal items: Avoid sharing items such as towels, bedding, or grooming tools with your dog, especially if they have an active staph infection.
-
Seek veterinary care: If you suspect that your dog has a staph infection or any other skin condition, consult a veterinarian promptly. Early diagnosis and appropriate treatment can help prevent the infection from spreading and minimize the risk of transmission.
By following these preventive measures, you can help reduce the risk of transmission between dogs and humans. It’s important to remember that staph infections in dogs are generally treatable and rarely cause severe illness in humans. However, if you have any concerns or questions, it’s best to consult a healthcare professional or veterinarian for personalized advice and guidance.
Severe Infections and Care
In some cases, staph infections in dogs can progress to more severe stages, requiring specialized care and treatment. Understanding the symptoms of deep infections and the available intensive treatment approaches is crucial for addressing these more serious cases effectively.
Deep Infection Symptoms
Deep staph infections in dogs may exhibit additional symptoms beyond the superficial skin-level infections. These symptoms may include:
- Fever
- Skin sensitivity
- Lethargy
- Shivering
- Decreased appetite
- Draining tracts
It is important to note that these symptoms may vary depending on the severity and location of the infection. If you suspect your dog has a deep staph infection, it is essential to seek veterinary care promptly. Early detection and intervention can help prevent the infection from spreading and causing further complications.
Intensive Treatment Approaches
When dealing with severe staph infections in dogs, intensive treatment approaches may be necessary. The specific treatment plan will depend on the severity of the infection and the veterinarian’s assessment. Here are some common intensive treatment approaches:
-
Topical Therapies: For milder cases, topical treatments like medicated antibacterial shampoos, wipes, mousse, ointments, and sprays may be prescribed. These help to control the infection and promote healing of the affected areas.
-
Systemic Antibiotics: In more severe cases or when topical treatments are not effective, oral antibiotics may be prescribed. Systemic antibiotics work to combat the infection from within the body, targeting the bacteria causing the staph infection.
It’s important to note that antibiotics should be used under the guidance of a veterinarian and administered for the full duration of the prescribed treatment to prevent antibiotic resistance.
In cases where the infection is particularly severe or not responding to treatment, a dog may require hospitalization. Hospitalization allows for more intensive care, including intravenous antibiotics and additional supportive measures to aid in the recovery process.
Remember, treating deep staph infections in dogs requires a comprehensive approach that addresses both the infection and any underlying factors contributing to the condition. Follow your veterinarian’s guidance, monitor your dog closely, and provide the necessary care and attention to help your furry friend recover.

Research Insights
When it comes to understanding the transmission and colonization of staph infections in dogs, research provides valuable insights. Let’s explore two key areas: transmission studies and colonization comparisons.
Transmission Studies
Numerous studies have investigated the transmission of staphylococcal infections between humans and dogs. In households with human S. aureus carriers, the transmission rate of S. aureus between humans and dogs was found to be 19.0%, lower than the human-to-human transmission rate of 29.0%. This suggests that while transmission can occur between humans and dogs, it is relatively less common.
Additionally, S. pseudintermedius, a staphylococcal species commonly found in dogs, was isolated from 42 dogs (37.5%) in households, but only from 1 human (0.6%). Whole-genome sequencing revealed a strong relatedness between the isolate found in the human and a canine isolate from the same household. These findings highlight the potential for cross-species transmission within a household.
In another study involving dogs and their owners visiting a veterinary practice, nasal carriage of S. aureus was detected in 3 out of 17 humans and 2 out of 17 dogs. However, S. pseudintermedius was obtained from 6 dogs but not from humans, indicating a higher prevalence of S. pseudintermedius in dogs compared to humans (NCBI).
Colonization Comparisons
Comparing colonization rates of staphylococcal species between humans and dogs provides further insights. In households owning dogs, 36.9% of humans were found to carry S. aureus, with 66 out of 179 humans and 10 out of 112 dogs carrying the bacteria. However, methicillin-resistant S. aureus (MRSA) was detected in only 1.1% of humans, and not in dogs (NCBI). This suggests that while S. aureus colonization can occur in both humans and dogs, the presence of MRSA is relatively rare.
These research insights contribute to our understanding of staphylococcal transmission and colonization dynamics between humans and dogs. While transmission can occur, it appears to be less prevalent than within-human transmission. Understanding these factors can help guide preventive measures and promote responsible pet ownership.
