Dogs have found themselves in an odd predicament by living with humans. In the wild, dogs don't need humans to achieve balance. They have a pack leader, work for food and travel with the pack. When we bring them into our world, we need to help them achieve balance by fulfilling their needs as nature intended. This takes exercise and discipline before affection, and always maintaining your calm, assertive pack leadership.

People who live in the now; those people make things happen.

Homeless people's dogs are more knowledgeable than dogs in Beverly Hills. Why? Because they explore, they move forward, they go through the ups and downs in life. A dog in a wealthy environment, there is no downs except what he lives.

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.

To me dogs are not the students, not the ones that need training. To me a dog is a teacher of life, who teaches us the principles of the most important moral values; honesty, integrity, loyalty, trust, respect and love.

Birth, life, death is a cycle. And they're all beautiful, you celebrate all of them. Animals do grieve, but they move on. That's the lesson behind animals.

I do think there are some dogs - although it's very, very rare - that do have to be kept away from all other dogs and all humans except for the one strong pack leader whom they trust. But I think I've run into less than a handful of dogs that were like that in my entire career.
