A dog was presented for weight gain, hair loss, polyuria, and polydipsia. The owner is also concerned about the loss of the dog’s ear tip. She reports the ear tip bleeds, becomes necrotic, heals, and then the cycle repeats. Physical examination of the ear tip revealed that approximately one-third of the right ear tip has been sloughed as a result of these cycles.
