Why is my dog gnawing at his tail?

Why is my dog gnawing at his tail?

Your dog may be biting at his tail due to behavior issues. Dogs that are stressed or anxious may bite, gnaw or lick at their skin. A new pet or person in the household, fireworks, or a household move can cause a dog a great deal of stress.

How do I stop my dog from chewing his tail raw?

When you notice your dog chewing on its tail, use the stop or no command. When your dog stops chewing its tail after you give the command, reward it with a treat or toy. When your dog starts to mess with its tail, distract it with play or a 10 to 15 minute training session.
