feedback3="'''Incorrect.''' Acral lick dermatitis, also called lick granuloma is caused by physical not chemical damage. It mostly occurs in dogs due to constant licking or chewing. Areas most affected are carpal, metacarpal, metatarsal, radial or tibial areas, usually just a single lesion. The correct answer is contact dermatitis, which results from exposure to chemicals, not an immunologic reaction. It grossly appears as erythematous patches and papules and occasionally vesicles distributed on any areas in contact with the irritant. This is often the ventral abdomen, chest, paws and chin, but this varies from dog to dog and depends on what the initiating agent is.
