I bought this book and Bruce Fogle's 'The Dog's Mind' at the same time and they are two very different books.
This is an excellent book to get involved with the general arguement of who's helping who in the human-dog relationship.
The Coppinger's really made me think, at the very end, if by getting a dog I was doing the right thing. A very valid question we should all ask ourselves as these animals need us for all the guidance, care, shelter, food and love throughout their lives.
A very detailed book that all current or future canus familiaris owners should read in order that they can to their best for their best friend.
