James B. Spencer. 231 pages H/C. As an amateur trainer, you have many advantages that a pro can envy. For example, the amateur can develop greater rapport with his or her dog. He has more time, so he does not need to use pressure techniques. He even has better access to the training grounds best suited to the initial stages of almost every phase of training. Spencer helps you make full use of them, and get top notch results with kinder, gentler training methods. With the help of this book, your retriever, too, will become a great retriever.
