If you need this book, say you have a new foster dog or a rescue dog coming into your home, it is a fantastic quick guide to everything you will need to do or need to know to get your dog settled in. I've been a volunteer dog trainer for eight years, so I knew most of what McConnel/London talked about. However, I have never fostered a dog before. Now I have my first foster dog. To a casual eye he seems well adjusted and friendly, but if you know what you're looking at you see he's freaked out and cuddly when it's safer to be submissive. He's barking and growling to any threat that is slightly more removed. This book helped me understand what is in my own house, and it's helping me have the patience to deal with it. ( )
