Pyoderma in Dogs: What You Need to Know

Posted: 02/18/2025 | BY: Jenna Bruce | Categories: Dog , Health problems , Pet care

If your dog has ever had itchy, red, or crusty skin, you might have come across the term “pyoderma.” While it sounds complicated, pyoderma is actually a common skin infection in dogs. The good news? It’s treatable! The bad news? If left unchecked, it can cause a lot of discomfort for your furry friend. Let’s dive into the topic of pyoderma in dogs, why it happens, how to treat it, and—most importantly—how to prevent it from coming back!

What is Pyoderma in Dogs?

Pyoderma literally means “pus in the skin.” It’s a bacterial skin infection that leads to redness, irritation, sores, and sometimes a nasty smell. The infection can be superficial (affecting only the top layer of the skin) or deep (going further into the skin layers).

What Causes Pyoderma in Dogs?

Several things can set the stage for pyoderma in dogs. The most common causes include:

  • Bacterial infections – Most cases of pyoderma are caused by bacteria, typically Staphylococcus pseudintermedius. When a dog’s skin barrier is compromised, bacteria can take over.
  • Allergies – Dogs with food allergies, environmental allergies, or flea allergies often develop pyoderma due to excessive itching and scratching.
  • Parasites – Fleas, mites, and ticks can break the skin barrier, making infections more likely.
  • Underlying health conditions – Hormonal imbalances (like hypothyroidism or Cushing’s disease) can weaken the skin’s defenses.
  • Poor grooming – Dogs with matted fur, excessive skin folds, or dirty coats are more prone to skin infections.
  • Moisture buildup – Dogs that swim often or have skin folds (like Bulldogs or Shar-Peis) may develop pyoderma due to trapped moisture.

Symptoms of Pyoderma in Dogs

If your pup is dealing with pyoderma, you may notice one or more of the following:

  • Red, inflamed skin
  • Pustules (small pus-filled bumps)
  • Hair loss in patches
  • Scaly or flaky skin
  • Itching and scratching
  • A strong odor coming from the affected area
  • Darkened skin (chronic cases)

Types of Pyoderma

There are different types of pyoderma, depending on how deep the infection goes:

  • Surface pyoderma – A mild infection that affects only the outermost skin layer. This can include conditions like hot spots.
  • Superficial pyoderma – Involves the hair follicles and upper skin layers. This type is common in allergic dogs.
  • Deep pyoderma – A more severe infection that affects deeper skin layers, often leading to painful sores and draining wounds.

How is Pyoderma in Dogs Diagnosed?

Your vet will likely diagnose pyoderma through:

  • A physical examination – Checking the skin for signs of infection.
  • Skin cytology – Examining skin samples under a microscope to identify bacteria or yeast.
  • Bacterial culture – In chronic or severe cases, a culture may be taken to determine the best antibiotic treatment.
  • Underlying condition testing – Blood tests or allergy testing may be recommended if an underlying issue is suspected.

Treatment Options for Pyoderma

Luckily, pyoderma is treatable! The right approach depends on the severity of the infection and the underlying cause.

1. Antibiotics

Since pyoderma is a bacterial infection, vets often prescribe antibiotics. It’s crucial to complete the full course of medication—even if your dog looks better—to prevent antibiotic resistance.

2. Medicated Shampoos

Bathing your dog with an antibacterial shampoo (containing ingredients like chlorhexidine or benzoyl peroxide) can help clear up the infection. Your vet may recommend bathing your pup (ONLY with dog-safe shampoo) a few times a week during treatment.

3. Topical Treatments

Ointments, sprays, or medicated wipes may be prescribed to apply directly to affected areas. This can be especially useful for mild cases or localized infections.

4. Addressing Underlying Causes

  • If allergies are to blame, your vet may recommend antihistamines, allergy shots, or diet changes.
  • If parasites are the issue, flea and tick prevention is essential.
  • If a hormonal imbalance is detected, managing the condition with medication can help prevent future skin infections.

5. Lifestyle and Grooming Adjustments

  • Regular grooming can prevent moisture buildup and mats that harbor bacteria.
  • Keeping your dog’s skin dry and clean (especially after swimming) is key.
  • A balanced diet rich in omega-3 fatty acids may improve skin health.

Can Pyoderma in Dogs Be Prevented?

Yes! While some dogs are more prone to skin infections, you can take steps to reduce the risk:

  • Maintain good hygiene – Regular baths and grooming help keep skin healthy.
  • Use flea and tick prevention – These parasites can contribute to skin infections.
  • Manage allergies – If your dog has allergies, work with your vet to find the best treatment plan.
  • Provide a high-quality diet – Good nutrition supports a strong immune system and healthy skin.
  • Keep skin folds dry – If your dog has wrinkles or folds, use pet-safe wipes to keep them clean and dry.

When to See a Vet

If you notice signs of pyoderma, don’t wait too long before seeing your vet. While mild cases may clear up with basic care, deeper infections require medical treatment. The sooner you address the issue, the easier (and cheaper!) it will be to treat.
