Updated with the latest information on canine breeds recognized by the American Kennel Club, this lavishly illustrated volume is a treasure house of information for dog lovers, owners, breeders, and prospective buyers.  It begins with a detailed discussion of breed evolution, focusing on the physical and behavioral traits that distinguish one canine breed from another. The book's main section profiles more than 175 breeds, including 27 new breeds, arranged in the general categories specified by the AKC—Sporting Group, Hound Group, Working Group, Terrier Group, Toy Group, Non-Sporting Group, and Herding Group.  Each profile tells how and why the breed was developed, and how selection to perpetuate specific traits affects a dog's suitability as a pet.
