Picking Your Performance Puppy is more than a book! It also contains links to videos that demonstrate how structure determines movement and performance in dogs. This book is geared towards people who want to know more about what it takes to make a great performance dog. If you are getting ready to purchase a puppy, adopt an older dog or just want to know more about the dog you have, this book will help you understand what makes a great performance dog. If you have ever wondered why some dogs excel while others struggle and why some dogs have longer careers than others, Picking Your Performance Puppy will take the mystery out structure for performance and answer those questions. Never before has the performance dog sport world had a manual like this book. Picking Your Performance Puppy goes beyond traditional "conformational thinking" about a dog's structure. In my opinion this book is a must have resource for anyone selecting a new puppy or considering the impact of playing a sport with their dog. Susan Garrett Say Yes Dog Training Inc.
