This book is a fascinating examination of the familiar dog by a professor of biology, who is also a former sled dog racing champion and dog trainer, and his wife, who is also an expert at the raising and training of dogs. Studying where dogs came from, what they are and where they are going, the authors reach some startling conclusions. They reject that idea that Mesolithic hunters stole wolf puppies to originally domesticate dogs, instead following the flow of adaptation to suggest that the path of domestication leads through the Neolithic garbage dump!
After that, the role and attributes of modern dogs are examined. Finally, the explosion of genetic "diseases" among purebred dogs is examined, and its causes laid bare.
This is a fascinating look at dogs. Much that I have noticed about the dogs in my life has been explained to me, and a great deal of food for thought given. I highly recommend this book; it will answer many questions, including some you never thought to ask.
