Pyoderma in Dogs

Pyoderma is a skin condition that can cause a variety of symptoms in our furry friends, including papules and pustules that may look similar to human pimples. But perhaps the most noticeable sign of this condition is the itchiness that comes with it, causing our dogs to scratch or lick the affected areas.

The most common signs of pyoderma include red, raised papules or pustules; circular crusts; dry or flaky skin patches; hair loss; and itching. Other symptoms may include discharge from lesions, excessive scratching, and sores. Seek immediate veterinary care if your pet has any of these signs.

What Is Pyoderma?

Recognizing pyoderma in its early stages is essential for timely treatment. Look out for small, pimple-like bumps known as papules or pus-filled pustules on the skin.

These red, raised lesions are often accompanied by circular crusts, dry or flaky skin patches, hair loss, and itching. It’s important to keep an eye out for these signs, as pyoderma can cause considerable discomfort for your pet.

 What Are The Clinical Signs Of Pyoderma?

Pyoderma manifests in several ways, and it’s crucial to recognize these signs early on to initiate prompt treatment. Some clinical signs are:

What Are The Clinical Signs Of Pyoderma

  • Papules or Pustules: These are small, pimple-like bumps that emerge on your pet’s skin. They’re usually red, raised, and may have a pus-filled center.
  • Circular Crusts: Look out for areas where the skin has developed crust-like formations. These are dried deposits of serum, blood, or pus.
  • Dry or Flaky Skin Patches: If part of your pet’s skin appears dry or has flaking, it may be a sign of pyoderma.
  • Hair Loss: Pyoderma can affect the hair follicles, often leading to hair loss in certain areas.
  • Itching: Pets with pyoderma are likely to scratch incessantly due to the itching.

It’s important to consult a vet immediately if your pet shows any of these signs, as early treatment can prevent the condition from worsening.

What Causes Pyoderma In Dogs?

Pyoderma in dogs is often caused by bacteria, with the most common being Staphylococcus pseudintermedius, a type of bacteria that normally resides on a dog’s skin.

However, certain factors can lead to an overgrowth of this bacteria, triggering pyoderma. These include:

What Causes Pyoderma In Dogs

  • Underlying Allergies: Dogs with allergies are more likely to develop pyoderma. This is because scratching at itchy skin can cause micro-abrasions, providing an entry point for bacteria.
  • Parasites: Fleas, mites, or ticks can cause skin damage and irritation, making dogs more susceptible to bacterial infections.
  • Hormonal Imbalances: Conditions such as hypothyroidism or Cushing’s disease can compromise the skin’s natural defenses, leading to pyoderma.
  • Poor Grooming: Not cleaning your dog’s skin and coat can allow for bacterial overgrowth.

It’s worth noting that while any dog can develop pyoderma, certain breeds are more predisposed to this skin condition due to their genetic makeup. Always consult with your vet if you notice any unusual skin changes in your pet.

How Is Pyoderma Diagnosed?

A definitive diagnosis of pyoderma typically involves a combination of clinical signs, history, and definitive diagnostic tests. Vets often undertake a multi-step process to diagnose this condition.

Physical Examination

The first step in diagnosing pyoderma is a thorough physical examination of the pet. The vet will inspect the skin for any lesions, hair loss, and other signs of pyoderma.

They will also evaluate your pet’s overall health, as underlying conditions can often contribute to pyoderma.

Physical Examination

Microscopic Examination

After identifying potential lesions, the vet may collect samples for microscopic examination. This can include a skin scraping or impression smear, which helps identify the presence of bacteria or other infectious agents.

Microscopic Examination

Culture and Sensitivity Testing

In some cases, your vet may recommend a culture and sensitivity test. This test identifies the specific bacterium causing the infection and determines the most effective antibiotics for treatment.

Culture and Sensitivity Testing


In persistent or recurring cases, a biopsy may be necessary. This procedure involves taking a small sample of skin for examination under a microscope. It helps rule out other potential causes of skin lesions, such as cancer or autoimmune diseases.

Identifying pyoderma early and initiating prompt treatment can significantly increase the chances of your pet’s full recovery. Therefore, regular check-ups and maintaining a keen eye for any changes in your pet’s skin are crucial.


 How Is Pyoderma Treated?

The treatment of pyoderma primarily involves antibiotics to address the bacterial infection. However, it’s important to remember that each case is unique and the treatment plan may vary depending on the severity of the condition and the overall health of your pet.

Here’s a general idea of what you can expect when treating pyoderma in dogs:


Antibiotics form the cornerstone of pyoderma treatment. Your vet will prescribe a course, typically lasting 3-4 weeks, based on the bacteria involved and the severity of the infection.


Topical Therapy

Alongside antibiotics, topical therapy can help alleviate symptoms and speed up recovery. This can involve medicated shampoos, sprays, or wipes, often containing ingredients like chlorhexidine or miconazole.

Topical Therapy

Treating Underlying Conditions

If your pet’s pyoderma is due to an underlying condition, such as allergies or hormonal imbalances, treating these conditions is essential to prevent recurrence.

Follow-Up Visits

Regular follow-up visits are crucial during treatment to monitor your pet’s progress and adjust the treatment plan if necessary.

It’s also important to complete the entire course of medication, even if the symptoms have improved, to prevent recurrence.

Follow-Up Visits

 What Is The Prognosis For My Pet’s Condition?

The prognosis for pets with pyoderma is generally good, especially when detected and treated promptly. However, it’s essential to remember that each case is unique and recovery times can vary.

Treatment doesn’t just target the symptoms but also the underlying conditions contributing to pyoderma.

It’s crucial to adhere to the prescribed treatment plan and attend all follow-up visits to ensure a full recovery. Recurrence is possible, especially if the underlying cause isn’t addressed, so maintaining vigilance for signs of pyoderma is key in managing this condition.

Overall, with proper care and attention, pets can lead a comfortable and healthy life post-pyoderma.

What Is The Prognosis For My Pet's Condition

In conclusion

Pyoderma is a common but treatable skin condition in pets, most often dogs. Early detection and prompt treatment are key to managing this condition effectively.

This involves being vigilant for signs such as pimple-like bumps, circular crusts, dry or flaky skin patches, hair loss, and constant itching.

Following a comprehensive diagnostic process, a treatment plan typically involving antibiotics and topical therapies, along with treating any underlying conditions, will be prescribed.
