Query: Revolutionary methods have changed my house!

I came home from work one day and my wife was excited to see me as she said, "come look at this." She called our dog, a seven year old Westie, into his area where he is always reluctant to go. But this day he walked right in without making a scene. She told me she had seen Jan Fennell on television that day and had simply tried one of the concepts she talked about. We got the book, and immediately our Westie has settled right in to our new pecking order, and has significantly settled down.We are more than impressed with the insight that this book gives. It has greatly improved our relationship with our dogs, and I would recommend this book to any dog owners. Understanding the canine culture is fascinating.
