What is your diagnosis?

FIG 1. Crusting dermatitis on face and legs. Note the splayed legs

FIG 2. Onychosis, hyperkeratosis and cracking of the foot- pads

A 12-WEEK-OLD male English bull terrier was presented with a history of stunted growth, diffi- culty in swallowing, splayed feet and a non- pruritic dermatitis. A closer dermatological examination revealed erythema, crusting and alopecia on the bridge of the nose, muzzle and the feet (Fig 1). The nails were deformed and there was severe hyperkeratosis and cracking of the foot pads (Fig 2). Another pup from the same litter was presented for vaccination at the same time. It was bigger and did not show any abnor- malities.
