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.

Any successful corporation, if they adopt the three, they're going to be not just wealthy but they're going to be balanced. A lot of corporations adopt exercise, discipline, no affection. But you must maintain the three, because it's part of what you need. You need physical stimulation, you need mental stimulation and of course you need emotional stimulation.

When you're poor, you have nothing to lose and be afraid of. Holding onto the dream and having nothing to lose is what helped me succeed.

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.

Bill Gates can't control a high-level-energy dog, because his energy is very low, very calm. Very intellectual. A dog doesn't see that as leadership.

Dogs help you to appreciate the world around you. They smell the ground so intensely. They look at the trees as though they are seeing them for the first time. It helps us to remember the wonders that we take for granted.
