Book 348 pages color (multiple pictures) 19 x 23 x 2 cm. Divided into 3 parts containing data on the nature of dogs (fear, phobias, aggression toward dogs and humans) while telling the stories of different breeds of dogs that Cesar was busy with at the support, many useful and sound advice. This and some my favorite book. A must-have in his library if you want to be in symbiosis and have a dog good about yourself for the next 15 years!
