This is about dogs, how they communicate with people and each other. It shows when and how dogs evolved, how dogs differ from wolves, both genetically and behaviorally. It also explains how dogs perceive the world. The book is based on hard, cutting-edge science, but written in a clear narrative style. Laced throughout the book are actual stories of how dogs think, act, and perceive the world. Not only my dogs, but those I know are used to prove or disprove what scientists have discovered--and what scientists have discovered have disproved most of the myths of how dogs came to be the only species of animals that work for and die for another species, Homo sapiens.
