This is not a guide to care and training but a simple scientific study encompassing the relationship of the dog to man and the domestic dog's evolution from the wolf, ending with the breeding of mutations into different types of dogs. A tipoff to the approach is the acknowledgement of indebtedness to Konrad Lorenz. In the foreword, he says, ""this whole story is very nice indeed,"" a nice unscientific way of saying ""well done."" It is. The many photographs are doggy delights, and some of them are also informative.
