About Pyodermas in Dogs

Pyoderma is a type of bacterial skin infection. According to Pet Place, pyoderma can range from a mild irritant to a severe systemic infection. In all cases, veterinary treatment is required.

Types

Pyodermas are categorized by lesion depth. There are three types: surface (on the skin surface only), superficial (within the skin layer) and deep (below the skin layer).

Cause

According to Rural Area Veterinary Services, the most common cause of canine pyoderma is the bacterium staphylococcus, although E. coli can also invade previously compromised skin.

Risk Factors

Certain conditions place your dog at risk for developing pyoderma. Risk factors include parasitic infestation, allergies, poor hygiene, immune system disorder, hormonal dysfunction and trauma.

Signs

According to Pet Place, symptoms of pyoderma include red, itchy, painful skin lesions; pimples (may be pus-filled); blood blisters; crusty, scaly spots; and draining sores.

Diagnosis

Your veterinarian will make a diagnosis based on your dog's medical history and diagnostic tests. Tests may include a biopsy, lesion culture, cytology, complete blood count (CBC), skin scrapes and allergy tests.

Treatment

Generally, pyodermas are treated with antibiotics or an antifungal cream or shampoo. Dogs with widespread, deep pyodermas may require hospitalization, intravenous medication, fluid therapy and daily whirlpool baths.
