When attempting to find solutions to training problems in a rough collie showing active defense reflex behavior problems (see William Campbell's 'Behavior Problems in Dogs') I read this book. The author fails to take into consideration the differences between active and passive defense reflex dogs. At the time, a number of dog trainers in our area were focused on this approach to training. In class, I was required to reposition my dog physically rather than using vocal cues to correct his behavior (the Bauman approach). This absolutely does NOT work with an active defense reflex dog! You can't imagine the problems this approach to training caused for my dog. I later found William Campbell's book, figured out a proper approach to training my dog, and consequently put a CD on him. The 'Bauman' trainers had told me I'd never succeed, but they lacked the insight into dog behavior to problem solve outside their 'box'.
