I enjoyed this book in the beginning but the second half was a struggle. Those parts on historical attitudes towards dog's intelligence, and dog evolution were interesting. Then there were parts arguing for the intelligence and consciousness of dogs which seemed rather obvious to me. He then turns to intelligence but here the focus turns almost exclusively to intelligence as illustrated in obedience/training. His prejudice is that a dog is only tolerable as a companion or valuable as a dog as of function of its obedience. He does present an intelligence test and a personality test.
A couple of the anecdotes were great, almost worth reading the whole book. ( )
