An “entertaining and informative” look at the evolutionary biology that explains canine behavior, with photos included (Lynette Hart, author of The Perfect Puppy). What actually drives dogs to do the things they do? What’s going on in their fur-covered heads as they look at us with their big, expressive eyes? Biologist Raymond Coppinger and cognitive scientist Mark Feinstein know something about these questions, and this is their guide to understanding your dog and its behavior. Approaching dogs as a biological species rather than just as pets, Coppinger and Feinstein distill decades of research and field experiments to explain in simple terms the evolutionary foundations underlying dog behaviors. They examine the central importance of the shape of dogs: how their physical body (including the genes and the brain) affects behavior, how shape interacts with the environment as animals grow, and how all of this has developed over time. Shape, they tell us, is what makes a champion sled dog or a Border collie that can successfully herd sheep. Other chapters explore such mysteries as why dogs play; whether dogs have minds, and if so what kinds of things they might know; why dogs bark; how dogs feed and forage; and the influence of the early relationship between mother and pup. Going far beyond the cozy lap dog, Coppinger and Feinstein are equally fascinated by what we can learn from the adaptations of dogs, wolves, coyotes, jackals, dingoes, and even pumas in the wild, as well as the behavior of working animals like guarding and herding dogs. Isn’t it time we knew more about who Fido and Trixie really are? How Dogs Work provides some keys to unlocking the origins of many of our dogs’ most common, most puzzling, and most endearing behaviors.
