What is a dog?

the long version

"Exploring the natural history of these creatures, the Coppingers explain how the village dogs of Vietnam, India, Africa, and Mexico are strikingly similar. These feral dogs, argue the Coppingers, are in fact the real representative dogs, nearly uniform in size and shape and incredibly self-sufficient. Drawing on nearly five decades of research, they show how dogs actually domesticated themselves in order to become such sufficient scavengers of human refuse. The Coppingers also examine the behavioral characteristics that enable dogs to live successfully and to reproduce, unconstrained by humans, in environments that we ordinarily do not think of as dog- friendly."--From publisher description.
