The Perfect Dog is an enticing fantasy pooch. It's the dog that instantly learns to pee outdoors, never menaces or frightens children, plays gently with other dogs, won't jump on the UPS guy, never rolls in gross things, eats only the appropriate food at the right time, and never chews anything not meant for him. This dog does not exist.

I'm one of those people who has always struggled with emotions and revealing them. When my dog Orson died, I did this very male thing of 'It's just a dog and I'll just move on.' I was very slow to grasp the emotion. But Orson is the reason I started writing about dogs.

Owners who buy aggressive dogs for security may be kidding themselves: The chances that the victim of a fatal dog attack will be a burglar or human attacker are 1-in-177. The odds that the victim will be a child are 7-in-10.
