Used to Reduce or eliminate dog pulling on leash during walks or general obedience training. Martingale dog collars are also known as greyhound, whippet or humane choke collars. The martingale dog collar was designed for sighthounds because their necks are larger than their heads and they can often slip out of buckle collars. These collars have gained popularity among other breed owners in the recent past with many trainers now recommending them instead of choke chains or buckle collars. A martingale collar is made with two loops. The larger loop is slipped onto the dogs neck and a leash is then clipped to the smaller loop. When the dog tries to pull, the tension on the leash pulls the small loop taut, which makes the large loop smaller and tighter on the neck, thus preventing escape. Properly fitted, the collar will be comfortably loose when not in use.
