"Barron's Training Your Dog" titles offer breed-specific advice on virtually every aspect of canine training, including housebreaking, obedience to basic verbal commands and hand signals, retrieving, and walking the dog on a leash. These books also discuss humane methods for breaking a dog's bad habits. The German Shepherd is intelligent and a quick learner, which makes him highly trainable. However, training of this fine dog should begin early in life. German Shepherds are best suited to owners who are calmly authoritative and consistent in their training methods. There are colour photos on most pages.
