In life... we need to find a balance. You have to set rules and limitations - that is called discipline. And you have to practice that in all your worlds.
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.
We're already saying it's not the dog, but you need to adopt this lifestyle which is exercise, discipline, and affection.
