Do you practice leash correction or patience?

We used the leash to train our dog and now that he is almost 5 years old he is the best dog I've ever had. I used a choke collar. When I had trouble with him pulling and yanking me I put the collar up behind his ears. There is a nerve there that they dont much like getting touched. I'm not sure if that is what you are talking of. It works great. I feel the possitive reinforcement is telling him he is good at obeying my wishes. Every pet is different though. Good luck.
