A 9-year-old intact male Labrador retriever presented to Tufts Foster Hospital for Small Animals for further evaluation of history of painful gait, chronic atopic dermatitis/pododermatitis (for years) and the recent discovery of of increased liver enzymes (ALT =422 U/L, ALP= 377 U/L, AST =73 U/L) with a normal albumin and bilirubin. The dog had failed to respond to consecutive 3 week courses of clindamycin and cefpodoxime. On physical examination the dog was normal except for extreme difficulty in getting up and walked gingerly. He would not permit full examination of the feet, but a moist dermatitis and areas of ulceration were appreciated (Fig 2 A).
