Superficial inguinal pyoderma in a young dog (puppy pimples)

Pyoderma refers to any skin disease characterized by purulent infections. This disease may be classified as deep or superficial, depending on the degree of dermal involvement.

In areas where skin folds predominate, a moisture-associated dermatitis and intertrigo may develop secondary or be a primary initiator of pyoderma.

Pyoderma in dogs is usually associated with:

Pyoderma is commonly seen in young puppies due to Staphylococcus spp infections (puppy pimples), but can also occur with atopy and Demodex spp mange, as well as allergy to Ctenocephalides spp fleas.

Treatment is based on sensitivity to antimicrobial culture.

Most superficial cases are effectively managed with topical chlorhexidine shampoos and oral antimicrobials such as amoxycillin/clavulanate, clindamycin, cefovecin and trimethoprim-sulphamethoxazole.

In deep pyoderma, oral pradofloxacin, oral cefadroxil and subcutaneously injected cefovecin have a satisfactory outcome[1].

The majority of pyodermas appear to resolve regardless of methicillin susceptibility of S. pseudintermedius[2].
