i defintiely recommend that you start a new thread with a more applicable thread title -- you will get more responses that way...
What i found most effective against pulling is the stop and go method as well as the stop and redirect (not sure if its an official method or just something that worked for us): basically every time that our guy would start pulling i would stop or switch directions, the goal was to teach our guy that if he pulls, the last thing that he will get is to go to his 'destination' faster. It requires ALOT of patience, a 30 minute walk may take an hour ... but it really worked well, basically he eventually learned that to keep moving forward he needs to not pull because pulling would just slow him down even more... this has worked with both my guy and my parent's dobey
i am sure others may have other ideas. good luck and remember - patience!!!
