In America, dogs are viewed by their names first, breed second. And dogs live behind walls. It's an unnatural point of view.
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.
We're the only species who follow unstable leaders. This is true - it has little to do with America - around the world, pack leaders are unstable. Animals don't follow that.
Aggression is not a breed thing. It's a state of mind, and it comes from how the human is with the dog. There are four levels of energy, regardless of the breed: low, medium, high, very high. The idea is to get a dog in your same level or lower than you.
When I go and work with people, I never say, 'Your dog is changed for the rest of its life.' It's like a diet. You've got to maintain a discipline and ritual in your life to keep a certain figure.
The dog is a reflection of your energy, of your behavior. You have to ask, 'What am I doing?' That's the right question to ask.
