Query: read the fine print about training techniques

When I first flipped through this book I was surprised and dismayed to see that the author promotes the use of painful and potentially injurious collars such as the choke collar and/or prong collar. That alone was enough to make me return the book--NO dog collar should poke or choke! There's also lots of info about cats, which is legitimate enough, but since most readers will be training one or the other, and not both, this amounts to wasted text (for which you pay). I'd recommend going online and digging up some info on getting your dog into film or TV, and buying a book like Dog Tricks for Dummies in the meantime. Cute cover, but I returned this one because of the choke-collar issue. FYI, I have an energetic German Shepherd who I pleasantly and successfully trained 100% through positive methods. It is totally possible to do this--I don't care WHAT you're training for (TV, search and rescue, family pet, etc.).
