What Is a Staph Infection in Dogs?

A staph infection develops when Staphylococcus bacteria multiply and cause disease, most often in a dog’s skin. Staphylococcus pseudintermedius is a common cause of bacterial skin infections in dogs and can normally live on their skin without causing problems. When the skin barrier is disrupted by allergies, scratching, parasites, moisture or other conditions, these bacteria may cause inflammation and infection. Staph-related skin infections are a common form of pyoderma and may produce red bumps, pus-filled pimples, crusts, hair loss, itching or a strong odor. Infections may be limited to the skin surface and hair follicles or extend into deeper tissues. Treatment depends on the depth and severity of the infection and should also address any underlying cause to reduce the risk of recurrence.

Types

Dogs can develop several forms of staph infection, and each can affect the skin and underlying tissues differently. Some remain superficial and involve the outer layers of the skin, while others affect hair follicles or spread deeper into the skin, causing more painful and serious infections. Understanding the most common types can help pet parents recognize symptoms early and better understand treatment options and recovery expectations.

Surface Pyoderma

Bacterial overgrowth affecting the outermost skin, often associated with moisture, irritation or skin folds.

Superficial Bacterial Folliculitis

A common staph-related infection of hair follicles, causing red bumps, pustules, crusts and patchy hair loss.

Impetigo (Puppy Pyoderma)

A superficial bacterial infection commonly seen in puppies, producing small pus-filled bumps on the belly and other sparsely haired areas.

Skin-Fold Pyoderma

An infection developing in moist skin folds, commonly around the face, lips, tail or vulva, where friction and trapped moisture promote bacterial growth.

Hot Spots (Acute Moist Dermatitis)

Rapidly developing, red, moist and painful skin lesions caused by scratching or licking, sometimes complicated by secondary staph infection.

Mucocutaneous Pyoderma

Inflammation and infection around the lips or other skin-mucous membrane borders, causing redness, crusting, erosion and discomfort.

Deep Pyoderma

A more serious bacterial infection extending into deeper skin tissues, potentially causing swelling, ulcers, painful nodules and draining wounds.

Interdigital Furunculosis

Painful inflammation and deep lesions between the toes, often associated with damaged hair follicles and secondary bacterial infections, including staph.

Wound and Surgical-Site Infections

Staph infections that develop when bacteria enter cuts, injuries or surgical incisions, causing redness, swelling, pain or discharge.

Other Staph Infections

Staphylococcus bacteria can also cause infections in the ears, urinary tract and other tissues. Symptoms and treatment depend on the affected area.

Predisposed Dog Breeds

While staph infections can affect any dog, certain breeds are more susceptible due to skin folds, allergies, and inherited skin conditions. Breeds with wrinkled skin, dense coats, or a genetic predisposition to allergic skin disease may face a higher risk of developing recurrent bacterial skin infections.

Breed Type / Risk Group Breeds Notes on Risk Factors
Skin-Fold Breeds English Bulldog, French Bulldog, Pug, Shar-Pei, Basset Hound Deep skin folds can trap moisture, heat and debris, creating an ideal environment for bacterial overgrowth and recurrent staph skin infections.
Allergy-Prone Breeds Labrador Retriever, Golden Retriever, Boxer, West Highland White Terrier, Cocker Spaniel Dogs with atopic dermatitis or food sensitivities often scratch and damage the skin barrier, making secondary staph infections much more likely.
Breeds Prone to Oily or Seborrheic Skin Cocker Spaniel, Basset Hound, West Highland White Terrier, Dachshund, German Shepherd Excess oil, flaky skin and chronic inflammation can disrupt the normal skin barrier and encourage bacterial overgrowth, especially when grooming or skin care is inadequate.
Heavy-Coated or Moisture-Retaining Breeds Chow Chow, Newfoundland, Saint Bernard, Golden Retriever, Australian Shepherd Thick coats may retain moisture close to the skin, especially in hot or humid conditions, increasing the risk of irritation, hot spots and secondary staph infection.
Breeds Prone to Interdigital Skin Problems English Bulldog, Bull Terrier, Labrador Retriever, Shar-Pei, Boxer Recurrent paw licking, inflammation between the toes and follicular damage can lead to painful bacterial infections, including staph-related interdigital lesions.
Other Commonly Affected Breeds Shih Tzu, Lhasa Apso, Poodle, Miniature Schnauzer, German Shepherd These breeds may be more vulnerable because of chronic skin disease, grooming-related irritation, ear disease or inherited tendencies toward allergic or inflammatory skin conditions.

Causes

Staph infections in dogs typically develop when naturally occurring Staphylococcus bacteria multiply excessively due to a weakened skin barrier or underlying health condition. Common contributing factors include allergies, skin injuries, excessive scratching, moisture, parasites, and immune system disorders. Understanding these causes can help pet parents reduce infection risks, identify underlying problems, and prevent recurring skin infections.

Bacterial Overgrowth

Staphylococcus bacteria normally live on a dog’s skin, but they can multiply excessively and cause infection when the skin’s natural protective barrier is disrupted.

Allergies

Environmental allergies, flea allergies and food allergies can cause itching and inflammation. Repeated scratching damages the skin, allowing staph bacteria to cause secondary infections.

Skin Injuries and Scratching

Cuts, abrasions, insect bites, excessive licking and scratching can damage the skin barrier, creating opportunities for bacteria to enter and cause localized infections.

Moisture and Skin Folds

Trapped moisture, friction and poor airflow in skin folds or beneath dense coats can encourage bacterial overgrowth, especially in dogs with wrinkled skin or recurrent skin irritation.

Hormonal and Endocrine Disorders

Conditions such as hypothyroidism and Cushing’s disease can alter skin health and weaken normal defenses, increasing susceptibility to recurring bacterial skin infections.

Weakened Immune System

Immune-suppressing medications, chronic illnesses and certain immune disorders can reduce a dog’s ability to control bacterial growth, increasing the risk of persistent or severe staph infections.

Parasites and Chronic Skin Inflammation

Fleas, mites and other skin parasites can trigger itching, inflammation and skin damage. These changes make it easier for staph bacteria to cause secondary infections.

Symptoms

Staph infection symptoms in dogs can vary depending on the type, location, depth, and severity of the infection. Early signs may include redness, itching, small bumps, or pustules, while more advanced infections can cause hair loss, crusty skin, swelling, painful sores, and pus-filled lesions. Some dogs may also develop an unpleasant skin odor, excessive licking, or discomfort. Because these symptoms can resemble allergies, fungal infections, or other skin conditions, persistent or worsening symptoms should be evaluated by a veterinarian.

  • Red, inflamed or irritated skin
  • Small red bumps or pustules
  • Crusty, scabby or flaky skin
  • Patchy hair loss or thinning fur
  • Persistent itching and scratching
  • Excessive licking or chewing
  • Circular patches of hair loss
  • Unpleasant skin odor
  • Painful sores or draining lesions
  • Swelling, tenderness or skin discoloration
Neck & Shoulders Redness, crusting, itchy skin
Back & Coat Pustules, scabs, patchy hair loss
Rump & Tail Base Itching, sores, inflamed skin
Belly & Groin Red bumps, pustules, irritation
Ears Redness, discharge, odor
Muzzle & Lips Crusting, redness, sores
Chest & Underarms Red bumps, moist skin, irritation
Paws & Toes Licking, swelling, painful lesions

Staph infections can affect different areas of a dog’s skin.

Stages & Progression of Staph Infection in Dogs

Staph infections in dogs can progress at different rates depending on the depth and severity of the infection, underlying health conditions, and how quickly treatment begins. Infections may initially cause mild redness or small pustules but can develop into deeper skin infections with swelling, pain, ulcers, and draining wounds. Unlike cancer, staph infections are not assigned formal stages; veterinarians classify them by the layers of skin affected. Understanding how an infection progresses can help pet parents recognize worsening symptoms, seek timely treatment, and better understand recovery expectations.

Illustrative Staph Infection Progression

Barrier Surface Superficial Deep Skin damage Redness Pustules Crusting Deep sores Possible worsening of skin involvement (not a timeline) Depth of skin involvement Skin Barrier Surface Superficial Deep Infection
1

Skin Barrier Disruption

Allergies, scratching, parasites or skin injuries damage the protective barrier, allowing normally present staph bacteria to multiply more easily. Infection may not yet be present.

2

Surface Involvement

Bacterial overgrowth and inflammation affect the outer skin surface, potentially causing redness, moisture, irritation, itching or an unpleasant odor.

3

Superficial Pyoderma

Infection involves the epidermis or hair follicles, causing red bumps, pustules, crusts, circular scaling and patchy hair loss. Veterinary treatment is needed to control the infection.

4

Deep Pyoderma

Infection extends into deeper skin tissues, potentially causing painful swelling, nodules, ulcers and draining wounds. These serious infections require prompt veterinary care.

This chart is a simplified illustration of possible staph-related skin disease severity, not a formal staging system or a predictable timeline. Veterinarians classify bacterial skin infections by their depth and clinical presentation. Not every infection progresses through these steps, and appropriate treatment can prevent worsening. Persistent, spreading or painful lesions should be evaluated by a veterinarian.

Top Ways to Prevent Staph Infection in Dogs

Because staph infections in dogs often develop when the skin barrier is damaged or underlying skin conditions are left untreated, preventive care is essential. By maintaining good hygiene, managing allergies, preventing parasites, keeping skin folds clean and dry, and scheduling regular veterinary checkups, the risk of bacterial skin infections can be reduced. Proactive skin care also helps prevent recurring infections and supports healthier skin and coat.

Prevention Strategy Why It Helps How to Do It
Maintain Proper Skin & Coat Hygiene Regular grooming removes dirt, debris, and excess oils while helping maintain a healthy skin barrier and reducing conditions that encourage bacterial overgrowth. Brush your dog regularly, bathe as recommended by your veterinarian, and use gentle dog-safe shampoos. Avoid harsh soaps and excessive bathing that can irritate or dry out the skin.
Manage Allergies & Skin Conditions Allergies cause itching, scratching, and inflammation that weaken the skin’s protective barrier, increasing the risk of secondary staph infections. Work with your veterinarian to identify and manage environmental, food, or flea allergies. Follow prescribed treatments and address recurring itching or skin irritation promptly.
Keep Skin Folds & Coat Dry Moisture trapped in skin folds or beneath dense fur can contribute to irritation and bacterial overgrowth, particularly in wrinkled breeds. Gently clean and thoroughly dry skin folds, paws, and other moisture-prone areas. Dry your dog’s coat after swimming or bathing and check for redness or unpleasant odors.
Maintain Regular Parasite Prevention Fleas, mites, and other parasites can trigger intense itching and skin damage, creating opportunities for staph bacteria to cause infection. Use veterinarian-recommended flea and tick preventives appropriate for your dog. Schedule veterinary evaluations if you notice persistent scratching, hair loss, or suspected mites.
Prevent Excessive Scratching & Licking Repeated scratching, chewing, and licking can damage the skin barrier, worsen inflammation, and allow bacteria to invade irritated areas. Check your dog regularly for itchy or painful spots, keep nails trimmed, and seek veterinary treatment for persistent licking or scratching. Use protective collars when recommended.
Provide Balanced Nutrition & Maintain Healthy Weight Adequate nutrition supports normal skin function and healing, while maintaining a healthy weight can reduce excessive skin folds and friction. Feed a complete and balanced diet suited to your dog’s age and health needs. Maintain a healthy weight and ask your veterinarian whether dietary changes are needed for skin problems.
Keep Bedding & Grooming Tools Clean Clean bedding and grooming equipment help limit dirt, irritants, and bacterial contamination, supporting better hygiene for dogs prone to recurring skin infections. Wash bedding regularly, clean brushes and grooming tools, and avoid sharing grooming equipment between dogs with active skin infections. Keep resting areas clean and dry.
Monitor Skin & Schedule Veterinary Checkups Early detection of redness, pustules, crusting, and hair loss allows prompt treatment before an infection becomes more extensive or severe. Inspect your dog’s skin during grooming and report recurring or worsening symptoms to your veterinarian. Follow prescribed treatments and attend recommended rechecks to help prevent repeated infections.

Actionable Resources

If you want to prevent staph infections, reduce the risk of recurrence, or support your dog’s recovery, here are some helpful resources to explore under veterinary guidance.

  • Best Medicated Dog Shampoos: Antibacterial shampoos containing ingredients such as chlorhexidine may help manage bacterial skin infections when recommended by a veterinarian.
  • Best Dog Foods for Skin Allergies: Specialized diets may help manage underlying food allergies, reduce itching, and support skin barrier health.
  • Best Dog Flea Treatments & Medications: Effective flea control helps prevent scratching, skin damage, and secondary bacterial infections.
  • Best Probiotics for Dogs: Probiotics may support digestive health, particularly during antibiotic treatment, but they do not directly treat staph infections.

How Is Staph Infection in Dogs Diagnosed

Diagnosing a staph infection in dogs requires a veterinary examination to identify the bacterial infection, determine its severity, and investigate underlying causes such as allergies or skin disorders. Veterinarians typically examine affected skin and use cytology to look for bacteria and inflammation. Bacterial culture and antibiotic susceptibility testing may also be needed, particularly for recurrent, deep, or treatment-resistant infections. Key steps include:

1. Physical Examination

Your veterinarian examines the affected skin for redness, pustules, crusting, hair loss, swelling, and discharge. They also review your dog’s medical history, itching, previous skin infections, and any treatments already used.

2. Skin Cytology

Skin samples are collected using adhesive tape, impression smears, or material from pustules. A microscope is used to identify bacteria and inflammatory cells. Finding coccoid bacteria within neutrophils supports a diagnosis of bacterial skin infection.

3. Bacterial Culture & Sensitivity

For deep, recurrent, or difficult-to-treat infections, a bacterial sample may be sent to a laboratory to identify the organism and determine which antibiotics are likely to work. This is especially important when antibiotic-resistant staph bacteria are suspected.

4. Skin Scrapings & Other Tests

Your veterinarian may perform skin scrapings, hair examinations, or fungal testing to check for mites, ringworm, and other conditions that resemble or contribute to bacterial skin infections. These tests help rule out alternative diagnoses.

5. Underlying Cause Evaluation

Because staph infections often develop secondary to another problem, your veterinarian may investigate allergies, parasites, hormonal disorders, or immune-related conditions. Bloodwork, allergy assessments, or endocrine testing may be recommended depending on your dog’s symptoms and history.

6. Severity Assessment

Your veterinarian determines whether the infection is limited to the skin surface, involves the hair follicles, or extends into deeper tissues. This assessment helps guide treatment, including topical antiseptic therapy, systemic antibiotics when necessary, and follow-up examinations.

Early detection and prompt treatment are essential because staph infections in dogs are generally easier to manage before they spread into deeper skin tissues. Timely veterinary care can help prevent complications, reduce discomfort, and support faster recovery.

Nutritional Support & Supplements

Proper nutrition can play an important supportive role for dogs with staph infections by helping maintain healthy skin, a strong skin barrier, immune function, and overall well-being during recovery. Depending on your dog’s needs, veterinarians may recommend a complete and balanced diet and supplements such as omega-3 fatty acids, probiotics, and essential skin-supporting nutrients like zinc and vitamin E when appropriate. These may support skin health and recovery but do not replace prescribed antibiotics or other veterinary treatments.

Omega-3 Fatty Acids
May help manage skin inflammation and support the skin barrier, especially in dogs with allergies.
Zinc & Skin Health
Essential for skin repair and immune function. Supplement only if deficiency is diagnosed or suspected by a vet.
Vitamin E & Antioxidants
Support normal skin health and help protect cells from oxidative damage. Extra doses are not routinely necessary.
Probiotics & Gut Support
May support digestive health during antibiotic therapy but do not directly treat staph infections.
Omega-6 Fatty Acids
Essential fatty acids help maintain healthy skin and its natural protective barrier against irritation.
High-Quality Protein
Provides amino acids needed for skin repair, wound healing and normal immune function.
Skin-Supporting Nutrients
Adequate B vitamins, essential minerals and fatty acids help maintain healthy skin and coat.
Therapeutic Feeding Strategy
A complete, balanced diet or vet-guided elimination diet may help manage underlying food allergies linked to recurrent infections.
i

Important: Nutrition and supplements may support skin health and recovery but cannot cure a staph infection. Excessive supplementation can cause harm or interact with medications. Always consult your veterinarian before adding supplements or changing your dog’s diet. Active infections require appropriate veterinary treatment, including topical antiseptics or antibiotics when indicated.

Supportive care—such as proper skin hygiene, nutritional support, itch management, and treatment of underlying allergies—plays an important role in promoting skin healing, reducing discomfort, and preventing recurring staph infections. These measures do not replace veterinary-prescribed treatments, including topical antiseptics or antibiotics when necessary. Always consult your veterinarian before introducing supplements, home remedies, or changes to your dog’s treatment plan.

Treatment & Care

According to veterinary dermatology guidelines, the most effective treatment for staph infections in dogs involves topical antiseptic therapy, antibiotics when necessary, and management of underlying skin conditions. Treatment may include medicated shampoos or antiseptic wipes to control bacterial growth, oral antibiotics for deep or severe infections, and allergy management or parasite control to address contributing factors. Proper skin hygiene, follow-up examinations, and completing prescribed treatments are essential for successful recovery and reducing recurrence.

Medications

Common medications used to treat staph infection in dogs include:

Medication / Class Examples How It Is Used Important Considerations
Topical Antiseptic Shampoos Chlorhexidine, benzoyl peroxide, ethyl lactate Commonly used for superficial staph skin infections and pyoderma to reduce bacterial load on the skin and help remove crusts, debris, and excess oils. Usually used several times weekly or as directed by a veterinarian. Adequate contact time is important. Avoid the eyes and monitor for skin dryness or irritation.
Topical Antiseptic Wipes / Sprays / Mousses Chlorhexidine wipes, hypochlorous acid sprays, antiseptic mousses Often used for localized infections, skin folds, paws, and other hard-to-bathe areas to help control bacterial growth between baths. Helpful for maintenance and localized care, especially in recurrent cases. Prevent licking until the product dries if your veterinarian advises it.
Systemic Antibiotics Cephalexin, cefpodoxime, amoxicillin-clavulanate, clindamycin Used for widespread, follicular, deep, or more severe staph infections when topical care alone is not enough. Should be prescribed by a veterinarian and given for the full recommended course. Gastrointestinal upset may occur, and recurrent or resistant infections may require bacterial culture testing.
Topical Antibiotics Mupirocin, fusidic acid where available May be used for small, localized skin lesions, superficial wounds, or focal bacterial infections. Best reserved for limited areas rather than widespread skin disease. Overuse may contribute to resistance, and dogs should be prevented from licking treated areas.
Anti-Itch / Allergy Medications Oclacitinib, lokivetmab, veterinarian-selected antihistamines Used to help control itching and reduce scratching in dogs with underlying allergies that contribute to recurrent staph infections. These medications help manage the underlying trigger but do not kill staph bacteria directly. Treatment choice depends on the dog’s overall health and skin condition.
Parasite Control Medications Fluralaner, afoxolaner, sarolaner, other vet-recommended flea and mite control products Used when fleas, mites, or other parasites are causing itching, inflammation, and skin damage that predispose dogs to bacterial skin infections. Effective parasite control is an important part of preventing recurrence. Products should be used according to veterinary guidance and label directions.
Antifungal Medications Miconazole, ketoconazole, itraconazole May be used when a staph infection occurs together with a yeast infection, which is common in some dogs with chronic skin disease. These do not treat staph bacteria by themselves. Oral antifungals may have potential side effects and drug interactions, so veterinary monitoring may be needed.
Medicated Ear Treatments Veterinarian-prescribed otic medications with antibacterial, antifungal, and anti-inflammatory ingredients Used when staph bacteria are involved in ear infections or when bacterial overgrowth contributes to otitis externa. The eardrum should be evaluated before some products are used. Cleaning instructions and treatment duration should be followed carefully to avoid recurrence.
Corticosteroids / Anti-Inflammatory Therapy Prednisone, prednisolone, veterinarian-selected anti-inflammatory therapy May occasionally be used short term to help control severe inflammation or itch when clinically appropriate. These drugs do not treat the bacterial infection itself and may not be appropriate in all cases. They must be used cautiously and only under veterinary supervision.
Pain Management / Comfort Care Gabapentin, veterinarian-prescribed analgesics Used when deep or painful skin infections cause discomfort, especially in dogs with swelling, draining lesions, or sore paws. Pain-control plans are individualized. These medications improve comfort but do not replace treatment for the underlying infection.

Emotional & Environmental Support
Clean bedding, calm routines, comfortable resting areas, and reduced stress can help dogs remain comfortable during infection treatment and recovery.
Comfort & Recovery Support
Veterinary pain relief, preventing excessive licking, gentle hygiene, and follow-up care can reduce discomfort and help protect healing skin.
Important: Integrative and supportive therapies may improve comfort, support skin health, and help reduce recurrence, but they do not replace veterinary-prescribed antiseptics or antibiotics when indicated. Avoid applying essential oils, herbal preparations, or human skin products without veterinary approval. Always work with your veterinarian to develop a safe, individualized treatment plan.

Surgical Options

Surgery is rarely necessary for staph infections in dogs, as most cases respond to topical antiseptics, antibiotics when indicated, and treatment of underlying skin conditions. However, severe or deep infections may require surgical intervention to drain abscesses, remove infected or dead tissue, or treat wounds that are not healing properly. In some cases, a veterinarian may recommend a minor procedure to remove a foreign object contributing to recurrent infection. Your veterinarian will determine whether surgery is appropriate based on the infection’s depth, severity, location, and your dog’s overall health.

Abscess Drainage
Drains localized pockets of pus caused by deep bacterial infections, relieving pressure and pain while allowing infected tissue to heal.
Surgical Debridement
Removes dead, damaged, or severely infected tissue from deep wounds to reduce bacterial contamination and promote healthy tissue healing.
Foreign Body Removal
Removes embedded grass awns, splinters, or other foreign materials that may cause persistent inflammation, draining wounds, and recurring secondary staph infections.
Wound Exploration & Flushing
Allows veterinarians to examine deep or complicated wounds, identify hidden pockets of infection, and flush contaminated areas with appropriate sterile solutions.
Surgical Drain Placement
In selected deep wounds or abscesses, temporary surgical drains allow accumulated fluid and discharge to escape while the affected tissues recover.
Skin Fold Correction Surgery
May remove or reshape excessive skin folds in dogs with severe, recurrent skin-fold infections that cannot be adequately controlled through hygiene and medical treatment.
Biopsy & Tissue Sampling
Collects tissue from unusual, deep, or treatment-resistant lesions for microscopic examination and, when indicated, bacterial culture to guide diagnosis and treatment.
Reconstructive Wound Surgery
Skin flaps, grafts, or specialized closure techniques may be needed for large wounds after severe infection or tissue removal, once the infection is adequately controlled.
Surgery for Chronic Paw Lesions
In select cases of persistent interdigital furunculosis or draining tracts, surgery may remove damaged follicles or chronically affected tissue when medical treatment fails.

Emotional & Lifestyle Impact

A staph infection can affect a dog’s comfort, behavior, sleep, and daily activities, particularly when persistent itching, painful skin lesions, or inflammation are present. Dogs may experience increased scratching, excessive licking, restlessness, irritability, or reduced interest in play and exercise. Recurrent infections can also be stressful for pet parents due to ongoing treatments and veterinary visits. With proper veterinary care, gentle skin hygiene, and a comfortable environment, most dogs recover well and can return to their normal, happy routines.

For Dogs

  • Persistent itching and skin discomfort may disrupt sleep
  • Painful sores can reduce interest in play and exercise
  • Excessive licking or scratching may cause restlessness
  • Medicated baths and frequent treatments may cause temporary stress
  • Most dogs can return to normal activities as their skin heals

For Pet Parents

  • Concerns about recurring infections and treatment costs
  • Managing medicated baths, medications, and skin care routines
  • Monitoring symptoms and preventing excessive scratching
  • Working with a veterinarian to address underlying allergies
  • Providing patience, affection, and a comfortable healing environment
