Graeme Hall tackles two problems with dogs that bite. The first gets over excited when visitors arrive, and explores the new people by getting his teeth round their wrists. The Dogfather is clear he’s not being vicious, but he does need to be taught how to stay calm in exciting new situations.

The second dog is chihuahua Hulk, who Graeme recently met on the TV show Dogs Behaving Very Badly. Owners Kathryn and Craig catch Graeme up on how their training’s been going since he left. They originally called him in as their dog was scared of them, and reacting by biting.
