To use the leash as a half harness, pull stopper knot back to make a loop. Place over the dog head and place one paw through the loop. The ring is between the dog’s shoulders. Slide the Stopper Knot down to the ring. As a rule, keep the ring on the dog’s right side. You're pulling from the dog’s shoulders and not the neck. No more choking. Great for dogs that pull a lot. A short leash gives you better control in a crowded environment like your Local Farmers Market.
