Journalist Derr, whose March 1996 Atlantic Monthly article, "The Politics of Dogs," was the basis of this book, traces the history of the dog-human relationship. Describing the breeding/development of dogs from wild wolves to domestics of all sizes, shapes, and functions, he outlines dogs' natural instincts for herding, guarding, drug searching, etc., as well as the physical and mental characteristics required for each kind of activity. Derr's interviews with breeders, blind persons, and others who work with dogs provide firsthand examples of dogs at work and play. The author is quick to point out that dogs are individuals and that being of a specific breed does not guarantee personality or performance; he suggests careful selection before training. Derr's informal narrative style makes for easy reading of a complex subject.
