Great dvd for anyone wanting a well behaved dog. It's best suited for those bringing a puppy home but the techniques can be used for older dogs as well. I have a 2 1/2 year female pitbull (dog aggressive)and used the techniques they outline in the behavior section in order to correct her when showing aggression toward other dogs. Needless to say she much more well behaved around other dogs when out on our walks. As a result, she's much calmer and is finally able to enjoy the walks we take!The philosphy they teach may be a bit long at times but well worth listening to. This dvd is not meant for those people who are too sensitive to the type of physical correction they teach. They are by no means cruel or advocate physical punishment as a means to train BUT they do teach you the proper way to physically correct them in a way that does not hurt the dog but gets their attention. Their techniques work period! My dog and I are much happier as a result of this dvd.JG
