Owners lavish love on their pets, which is why so many go from non-aggressive pups to being out of control when they're older. People just don't realise their dog must respect them as leader of the pack.

Americans are very big about loving the dog first, so when you tell them you have to set rules and limitations, a lot of people believe it's going to hurt their feelings. They're actually looking for you to be the pack leader.

Oprah is a wealthy person, pack leader of the human world. So many see her as the dominant one, as the authority figure. The way I view her energy, seeing her on TV, is a very calm, quiet energy. You need, in order to gain control, higher energy than your dog.

The pack is very important for a dog. Once you give him the right pack and the right energy, you look at him.

People say I train dogs, but in many ways I train people.

Dog parks can be a fantastic way to socialize your dog, but it's important for owners to understand that a dog park isn't exercise and isn't a substitute for walk. A visit to the dog park is fun - play time.
