Cutaneous diseases of the paw

Cutaneous disorders of the paw remain a challenging clinical entity. The presenting appearance of the various etiologies is often amazingly similar. However, by using a standardized diagnostic method, one can systemically rule in or out the more common causes and objectively establish a working differential diagnosis. Therapeutic and prognostic considerations are dependent on the etiology. General dermatologic principles apply to the paw as well as to the other areas of the skin; however, because of the known frequency of relapses and therapeutic difficulties, one must approach any case of pododermatitis with a realistic attitude and anticipation of prolonged therapy.
