In my classes, there is a great deal more happening than the usual sit-down-stay-come. I talk about learning theory, redirected aggression, Premack principle, the work of Turid Rugaas, etc., etc., only in puppy k and beginners classes. To make the transition from other training methods as easy as possible (for you and your dog), I would recommend that you come to a beginners class before moving on to the more advanced classes. That way we are all on the same page in terms of positive training and group knowledge.
