Pyoderma in Dogs

Pyoderma means “pus on the skin.” It is associated with a skin infection and the formation of pus. Bacteria are the causative agent of pyoderma and are common in dogs.

Until now, science has not yet recognized the exact cause of pyoderma. The vet associates it with the immune system disorder. Pyoderma alone is not contagious. It cannot be transferred from one dog to another.

If you want to know what are the underlying causes and symptoms, and how can we treat it, then this article is for you.

What are the causes of pyoderma in dogs?

It is a normal condition when there are bacteria on your dog’s skin, but it is not normal when these bacteria cause infection on your pet’s skin.

Staphylococcus bacteria usually cause pyoderma in dogs. As we all know, staphylococcus is resistant to many drugs. However, it can still be cleared from the body very easily. The bacteria on the dog’s skin infect it when the skin is damaged or broken, and this is how the dog gets pyoderma.

Bacterial skin infections also occur when normal skin bacteria have been changed or altered. It also occurs due to the impaired blood supply to the skin or due to suppression of the immune system.

Some common causes which can be the source of pyoderma in dogs are

  • Unhealthy nutrition
  • Hypersensitivity to food, environmental factors, and fleas
  • A hormonal disorder like hypothyroidism
  • Immune-suppressing drugs
  • Mites
  • Wound
  • Presence of foreign body under the skin

Sign and symptoms

The most common sign and symptoms of pyoderma in dogs are the appearances of pustules or papules on the surface of the skin. These papules resemble grains. They are often red in color and filled with white pus. Excessive flaking is also the most common sign of pyoderma.


With scaly patches of skin, hair loss is also seen in the pyoderma. Pyoderma is extremely itchy in some cases. A type of pyoderma that is found mainly in puppies can also be found in adult dogs.

Dogs with pyoderma feel slightly itchy, but they are usually in good health. Red bumps and groin on the abdomen are seen in pyoderma.

The signs of pyoderma can be seen at a variety of points. It can be in one place, or it can cover your pet’s entire body. The areas of your pet’s body that are most likely to affect are the folds of the skin, such as the toes, chin, and lips.

The diagnosis is usually based on the clinical signs observed in your dog. Steps to identify any predisposing cause should be included in the diagnosis of pyoderma.

To determine your dog’s specific allergies, many tests are performed that include blood tests, antibiotic sensitivity tests, urine tests, skin culture, and fungal culture.


In the treatment session, we have to shave the total affected area to better understand the damage and for the adequate absorption of the topical medication.

Complete body cleansing with a veterinary prescribed antibacterial shampoo is included in the first step. A continuous bath routine is also important to clear the infection.

Antibiotic therapy for three to four weeks is a typical treatment for your dog suffering from Pyo-derma. Lower doses of steroids may also be prescribed. Aerosols that contain benzoyl peroxide or chlorhexidine also play an important role in the treatment of pyoderma.

Dry, padded bedding should be provided to your pet. Healthy eating and nutrition also play an essential role in the recovery of pyoderma.
