I disagree with their collars and chain throwing, etc, and all that "baaa" stuff isn't that different for the $$$. That franchise is expensive and often trainers don't know that much, don't respond or return calls, and other are fine - if you use their collar and so forth. But don't let ANY trainer talk you into training with a collar on a Yorkie. Not necessary. They are no better than any other big business dog training and have some bad
PR, just like all of them. I don't know if they still use it but growling at your own dog to train it just isn't necessary!
