I, personally, am not a big fan of sending your dog off for training. First off, I think a good majority of the bond made between an owner and their dog is through the training process...that's where they learn to listen to you and work alongside you. Also, I'm with Kay on the fact that the moving around and shuffling is not a good idea. If anything, it could have an even worse effect on him and make him even harder to train.

But hey, it's up to you.
