My Dog Keeps Chewing His Tail. It is extremely red and irritated, and some of her hair is falling out. Since dogs cannot talk, they cannot make their needs or desires plain to us in any simple or intelligible way.

When your dog keeps biting his bum and tail, it could be a bad habit that he has picked up. A fractured tailbone or hurt tail would cause your pup great distress, but they won’t be able to inform you. When your dog stops chewing its tail after you give the command, reward it with a treat or toy.
