Drawing on insight gleaned from forty-five years of raising, training, and studying the behaviors of dogs worldwide, Lorna and Raymond Coppinger explore the fascinating processes by which dog breeds have evolved into their unique shapes and behaviors. Concentrating on five types of dogs -- modern household dogs, village dogs, livestock-guarding dogs, sled dogs, and herding dogs -- the Coppingers, internationally recognized canine ethologists and consummate dog lovers, examine our canine companions from a unique biological viewpoint. Dogs clearly points the way for dog lovers, dog therapists, veterinarians, and all others who deal with dogs to understand their animals from a fresh perspective.

How did the domestic dog become a distinct species from the wolf? Why do different breeds behave differently? Most important, how can we improve the relationship between humans and dogs?

The authors show how dogs' different abilities depend upon the confluence of their nature and nurture -- that both genetics and the environment play equally key roles. They also reveal that many people inadvertently harm their canine companions because they fail to understand dogs' biological needs and dispositions.

Dogs is a highly readable biological approach by noted researchers that provides a wealth of new information about the interaction of nature and nurture, and demonstrates how unique dog behavior is in the animal world.

Dr. James D. Watson winner of the 1962 Nobel Prize in Physiology and Medicine and author of The Double Helix Ray and Lorna Coppinger's Dogs should forever change the way we look at humans' ""best friends."" Both dog owners and those who want to be will profit by their description of how genes and environmental signals make the dog very much not a wolf.
