Thanks everyone , last night we where practicing ( for my sisters gait lol) we noticed similar to Billy's situation, that when chain is placed high on neck ( with no dogs around ) he does not trot right his head is not too low but he does not have his springing action with head up. he goes into a fast gait if as he was pulling a cart. At the UKC show he did not do this ( he was showing off staying at attention because of new place smells and other dogs ) we took chain off and he gaited perfectly in a circle with out leash lol. So we took chain again and just let it be on his neck and not under his jaw/high on neck. he did better with it sitting in the middle/ lower neck.
I thought it was funny. We will see how he acts at the AKC show , he is becoming a man now scent marking ( outside of course) humping other dogs !!!!! Last time we took him to dog park he went on a crazy humping spree , he did not listen either so I will be training him more in that area. I did correct him and made him stay by my side I was really upset with him , but like cesar millan says you can't get frustrated or upset because dog picks up on it
