Strategies for management of recurrent pyoderma in dogs.

Staphylococcal skin infection (pyoderma) is a common clinical problem in dogs. The infection can be either superficial or deep. Most cases of staphylococcal pyoderma occur secondary to a definable underlying cause. Treatment consists of finding the underlying cause and correcting it, if possible, and treating the pyoderma with antibiotics. Antibacterial shampoos may be used as adjunct treatment, but corticosteroid drugs should not be used. When canine pyoderma recurs in the absence of an identifiable underlying cause, several treatment strategies can be effective in eliminating recurrence or limiting its severity. Frequent antibacterial shampoos are an easy and sometimes effective method. Immunomodulatory drugs are variably effective. Some commercially available bacterins are clearly helpful in treating recurrent pyoderma. As a last resort, the clinician may opt to keep the patient on long-term antibiotic therapy. Such therapy may promote development and dissemination of resistant strains of Staphylococcus and should be used only if absolutely necessary.
