Book excerpt: We keep dogs and are kept by them. We love dogs and (we assume) we are loved by them. Even while we see ourselves in dogs, we also treat them in surprising ways. On the one hand, we let them into our beds, we give them meaningful names, make them members of our family, and buy them the best food, toys, accessories, clothes, and more. But we also shape our dogs into something they aren't meant to be. Purebreeding dogs has led to many unhealthy pups. Many dogs have no homes, or live out their lives in shelters. How is it possible we can treat the same species in these two totally different ways? In this book the author reveals the odd, suprising, and contradictory ways we live with dogs.
