It is tougher for a dog to live without rules because he doesn't know what is expected of him. It is the mind, the body, the heart, not just the heart. Love is not enough.

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.

I have always been honest with my fans, which means being open about any struggles I have had along the way.
