I dislike the concept of using force on a dog, especially a puppy. This book still preaches the outdated Alpha Roll, which teaches a dog to use force and is based on the Wolf Pack model. Domesticated dogs aren't wolves, and would you use everything a wolf uses? Does that mean you'd feed your dog by eating first, then regurgitating so the puppy can eat? Nonsense.Ian Dunbar, Joel Walton, Patricia McConnell and Pat Miller have much better training books.
