I have a 10 year old Brittany Spaniel and he has been licking his right hind leg since August. We have gone to the vet and was given bitter apple (he licked it off), Prednisone (no help) and even wrapped his leg with gauze and covered it with deodorant to deter him from licking. Nothing works. He has now licked a sore on his leg. The vet says that he does this for similar reasons humans bite their nails. Any help would be greatly appreciated. I'm afraid he's going to lick his leg off. Thank you for your time.
