Does your dog love you? It really seems like it, but for years, scientists have resisted that conclusion, warning against anthropomorphizing our pets. Enter Clive Wynne, a pioneering canine behaviorist whose research is helping to usher in a new era: one in which love, not intelligence or submissiveness, is at the heart of the human-canine relationship. Drawing on cutting?edge studies from around the world, Wynne shows that affection is the very essence of dogs, from their faces and tails to their brains, hormones, even DNA, and it is now possible to understand more about dogs' unique origins, behavior, and needs than ever before.
