To me this is someone who is not dominatein their home life so wants to show that they can be dominate over something. And this being a dog. Come on this is bordering on animal cruelity in my mind. Get your dog and yourself out of this person. I reakon that this will break your dogs spirts real quick.
So please leave this training camp. Put yourself in your dogs shoes and what would you do. I know if someone wanted to push me over because they want to be the dominate one. I would be doing more than pushing back. Remember the dog cant talk and you are supposed to be the one who can talk for your dog and not be a push over by anyone at all.
