A pioneering canine behaviorist draws on cutting-edge research to show that a single, simple trait--the capacity to love--is what makes dogs such perfect companions for humans, and explains how we can better reciprocate their affection. "Lively and fascinating . . . The reader comes away cheered, better informed, and with a new and deeper appreciation for our amazing canine companions and their enormous capacity for love." --Cat Warren, New York Times best-selling author of What the Dog Knows Does your dog love you? Every dog lover knows the feeling. The nuzzle of a dog's nose, the warmth of them lying at our feet, even their whining when they want to get up on the bed. It really seems like our dogs love us, too. 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 his lab and others around the world, Wynne shows that affection is the very essence of dogs, from their faces and tails to their brains, hormones, even DNA. This scientific revolution is revealing more about dogs' unique origins, behavior, needs, and hidden depths than we ever imagined possible. A humane, illuminating book, Dog Is Love is essential reading for anyone who has ever loved a dog--and experienced the wonder of being loved back.
