There are dog lovers, and then there are dog lovers. Behavioral scientists Raymond Coppinger and Lorna Coppinger have raised hundreds of dogs of various breeds, raced sled teams, and published professional and popular works on canine behavior. Dogs is their manifesto of canine evolution and treatment by humans, and it offers deep insight, provocative theories, and controversial ideas regarding our relationship with them. Though some of the material is most appropriate for readers with some zoological background, much of it is written for a general audience--one that cares about dogs not just for what they offer humans, but for their own sake.

Arguing that much of current thinking about dogs' evolutionary history is misguided, the authors share their own complex story of wolflike animals coevolving with permanent human settlements and only recently being subject to directed breeding and artificial selection. This is interesting enough, but they go on to take issue with the use and treatment of dogs, some of which they claim is bad for dog and human alike. Pure breeding, making companion animals of inappropriate breeds, and even some uses of disability assistance are assailed for neglecting genetic and other hardwired aspects of canine life. Surprisingly little is known for sure about dogs' lives and behavior, so the Coppingers' contribution is a welcome, if occasionally unsettling, eye-opener. --Rob Lightner
