We have one and use it only when teaching a young dog to walk at our side. We never have to do any correction with it, just the fact that it is there on the dog tells them we must walk by our master. With a regular collar, leather or choke chain our 10 month old male wants to meet and love each person he meets and does not care who is on the end of the leash. He goes with me often to town and loves the bank as he will set by the tellers counter and when they bring a bone for him he will put his front feet on the counter and take the bone ever so easy.. In fact if I go to town withour him everone wants to know where Shadow is.
