Bacterial skin infection (pyoderma)

What is pyoderma?

Pyoderma is an infection of the skin. It can occur as either superficial pyoderma, which involves the hair follicle, or deep pyoderma, which involves deeper levels of the skin. Many dogs in the UK suffer with episodes of superficial pyoderma - including acute moist dermatitis (hotspots) and skin fold dermatitis (intertrigo).

Why did my dog get pyoderma?

Pyoderma can occur for several reasons which include allergies, parasites and conformation, i.e., dogs with skin folds are more prone to disease between the folds. Certain breeds also have a predisposition to skin disease, some examples of which are below.

Breeds of dogs that are commonly affected by acute moist dermatitis ("hotspots") include:

Golden Retrievers
Newfoundlands
German Shepherds
Bernese Mountain Dogs

Breeds of dogs susceptible to skin fold pyoderma (intertrigo):

Pekingese, pugs, and bulldogs
Spaniels with lip folds

Acute moist dermatitis (hot spots)

Dog with hotspot

Acute moist dermatitis (hotspots) are usually created by the licking or chewing activity of the dog. Triggers that incite the dog to lick or chew are usually itchy, for example ear disease, full anal sacs, parasites (e.g. fleas) or an allergic reaction.

Lesions may not truly be infected as the bacteria are only found on the surface of the skin, but deep versions also occur.

Typically, dogs will transfer bacteria, usually Staphylococcus pseudintermedius, from the mouth or nose to the site.

Skin fold dermatitis (intertrigo)

Skin fold dermatitis (intertrigo) occurs when the folds of skin cause a warm, moist environment, perfect for microbial infection. Certain breeds are more commonly affected due to their conformation with dogs suffering from obesity and brachycephalic dogs with folds on their faces overrepresented.

Treating pyoderma

Pyoderma will need to be diagnosed by a vet. In some cases, they may take skin samples or swabs to help determine the best treatment. In most instances the vet will prescribe a topical gel or cream to treat. In more severe instances they may also prescribe a course of oral antibiotics or anti-inflammatories.

Preventing pyoderma

To prevent pyoderma recurring then some simple steps need to be followed:

• Ensure clean/dry bedding

• Shampoo your dog regularly with a veterinary recommended shampoo

• Regular brushing

• Use veterinary recommended antiseptics if needed

• Investigate and treat the underlying disease
