Chronic problem wounds of dog limbs.

Other dermatoses are capable of affecting the limbs and paws of dogs. One should approach the diagnostic workup of these cases in an organized manner, first obtaining a thorough history and performing a physical examination. A variety of diagnostic tests, including skin scrapings, cytology, fungal cultures, bacterial cultures, hematology, serum biochemical profiles, urinalysis, serology, radiology, histopathology, and direct immunofluorescence testing, may be necessary before a definitive diagnosis is reached. Therapy may be surgical, medical, or a combination of both depending upon the etiologic agent.
