This martingale dog collar keeps your dog safer than ever. Martingale collars are safer than choke chains or prong collars. Used with a leash or with your hand, the martingale collar tightens when your dog pulls and loosens when he stops, so it&##39;s only tight when it needs to be. These collars give you greater control and reduce the risk of your dog slipping out and escaping.
