Sophia's Newest Book
“Sophia Yin’s approach to dog training is a perfect meshing of the scientific theory and practical application. What is most important is her introduction to trainers of the significance of the person’s behavior and its effect on the dog’s learning ability. Sophia has done this better than anyone else, emphasizing in a very readable fashion the lasting effects of people’s actions on their dog’s behaviors. This is an important book for anyone who wants to maximize correct interactions with the pet.”

—Dr. Raymond Coppinger, PhD, Professor of Biology, Hampshire College, author of Dogs, A New Understanding Of Cainine Origin, Behavior and Evolution
