I have been "training" him from the first day he became part of the family. He has been in obedience class for 5 weeks. When he pulls ahead of me he is immediately corrected. He just doesn't seem to mind it. A snap of the lead gets his attention but he continues to pay no attention...I worry that his neck will become sore! Ironically he he is perfect with his sit and down stays, as well as other exercizes. Thanks for the advise.
