If I'm right, the only reason our species is still around is because of our friendship with the canines.

We have enforced a Darwinian process on wolves, turning them into the shy and elusive animals they've become. They didn't have that fear of us 30,000 years ago. We didn't have gunpowder; we had rocks. Wolves would have seen us as lunch, and we were weak and slow and tasty.

With my book 'How to Remodel a Man,' I was on Oprah, Fox News, the Early Show, and Good Morning America. Oprah was the best - an hour long segment. TV is so short; you answer a few questions, and then it's over. It feels like a hit-and-run with a camera.

When we adopt a dog or any pet, we know it is going to end with us having to say goodbye, but we still do it. And we do it for a very good reason: They bring so much joy and optimism and happiness. They attack every moment of every day with that attitude.
