I didn't read all the replies, but I have the same problem with the EZ Walk harness, but I think it's cause I can't get it adjusted right on Chip.

Have you tried a gentle leader? I have one for Smokey who is a BIG time puller and it works wonders. They don't like it, but it helps a lot. I know some people get concerned about the collar part, but the hook is actually underneath the nose - the collar won't hurt them because there is no pressure on the neck. When they pull, it pulls their head down towards the ground (because the hook is under the nose) and they stop... at least for awhile. When he comes back by your side, then you can reward him for walking nicely.
