Amazon.com description: Product Description: In order to understand people better, we often look to their past. Resi Gerritsen and Ruud Haak show that the same is true for dog breeds. By taking a look back through the history of those breeds most active in K9 work, Gerritsen and Haak reveal why the traits of each breed emerged to make them world class K9 workers.

Each chapter in this book examines the history, characteristics, training experience, and physical defects of the world’s best working breeds. Only through understanding a breed’s history can a K9 handler truly appreciate the different characteristics and capabilities of the dog they’re working with. Knowing this information is invaluable in training a dog in order to develop his full potential. To this end, the authors include a chapter devoted to the difference in training the increasingly popular Malinois versus the previous top K9 worker, the German Shepherd.
