Barking. Biting. Piddling. Digging. Dogs are wonderful companions, but they can also be challenging housemates. Dr. Gary Sampson has a message for owners: it's not the dog's fault. It's yours. He helps owners understand why their animal is acting -- or reacting -- in a certain way and explains how to change that behavior for the better. Using real-life examples from his practice, Sampson proves it's possible to convert that howling devil into an angel.
