Good afternoon, so we are stumped with our 8 month old pup, I know biting is a part of growing. He bites everything and correct him when needed to but he started biting his hind leg. He licks and bites the fur off, no flees or ticks and nothing that hurt him either. We took him to the vet to get checked out. We think it’s behavior, what would be the best way to handle this one? Would a muzzle be the best way or an e-collar? Any tips would be appreciated!
