Just wondering if anyone has any other ideas for what to do about some patches that are appearing on Rocky's elbows. The fur is missing and they look irritated. Not bleeding yet but I don't want it to get to that point. I believe it's from laying on the floor, which is wood. He has a huge orthopedic dog bed that he will not sleep on. (Waste of over a hundred bucks.) He either lays on the couch or on the floor. I've tried putting down towels and blankets and he won't lay on them either. I wonder if maybe he's losing sensitivity?
