My kids are around pit bulls every day. In the ’70s they blamed Dobermans, in the ’80s they blamed German Shepherds, in the ’90s they blamed the Rottweiler. Now they blame the Pit Bull.

I was blessed to grow up on a farm, and when you're a farm boy, exercise is part of your lifestyle. Like it or not, that environment makes you work out. On the farm, nature is your gym. You walk and run and swim and have to do a lot of work with animals too.

Little dogs bite more than big dogs but they get away with it.

There are two schools. The school where you go and open a book, and then there's the school of life. When you learn hands-on, often you don't understand why you do what you do and what's the word for that action.

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.

The reality is, if you have a high-level-energy dog, it's not going to be happy with a one-hour walk. Those types of dogs are going to require more than one hour of physical challenge in the outside world.

Dogs experience the world as it is, without judgement. When we learn to do the same, we make the world a better place.
