OK, so recently my beagle-mix had been licking the same spot on his left foreleg to the point where there's a small hotspot forming. I've heard that happened in dogs, but I'm not sure how it happens, or if it's an indication of something that needs a trip to the vet. Is there a way to get him to stop? Why do some dogs do this where they lick themselves at one spot over and over until a hotspot forms? Thoughts and advice on what to do about this?
