This martingale collar is equipped with two loops which are connected with O-ring to
attach a leash. When your dog tries to pull his head out of the collar, the tension on the leash pulls the
collar tight, which makes escaping almost impossible. When adjusted properly the dog is never choked. The collar
stays snug around the dog's neck (just behind the ears) until the pressure is decreased.
