Query: The Most Helpful Book I've Ever Read About Dogs

This is the most important, most helpful book I have ever read on the subject of dogs. I adopted my first dog 5 years ago from my local humane society. A lovely mixed breed, he turned out to be very violent. It was a tragic experience. I will never adopt another dog, from anywhere or anyone, without applying the tools Sue Sternberg shares in this book - no matter how cute the dog or popular the shelter. As a matter of fact, I would travel the thousand miles from my home to her shelter to adopt from her. This book is truly a gift to anyone planning to add a dog to their life.
