if you use a “choke chain” (actually it is called a check collar) or prong collar with your dog the idea is not to inflict pain but to apply gentle pressure to guide them. when your dog pulls against it, don’t pull back on it as hard as you can, that will only make them pull harder. when they pull, ease up and put some slack in the leash and give it a quick “snap” quickly pulling the leash back toward you. just enough to move the head, not yank them head, body and all. you may have to do this a couple of times to get their attention but it sure beats playing tug of war with an 80 lb dog. lol
