My Patented No Pull Harness design is very unique. I wanted a product that did not use pain, nor cause discomfort to the dog while walking. I designed the body strap to slightly tighten around the core of the body. The placement of the body strap was move further back onto the rib cage, out of the normally target the sensitive armpit area. The uniquely designed back part of the harness has 3 forms of connected pressure on the body of the dog as it pulls on the attached leash:  1. Direct Motion – Allows movement of the body strap to tighten and release pressure on the core of body.  2. Indirect Shoulder Motion – As movement of the back part of harness follows movement of leash toward the rear of dog. That movement causes the shoulder straps to slightly applies pressure over the shoulders down to the front of the chest point.  3.  Indirect Belly Strap Motion – As the front shoulder strap applies over the shoulders the movement continues down to the connected Belly Strap that is also connected to the body strap. This pressure is now affecting the entire core of the dogs body. You now have your dog total attention; Your dog will acknowledge that they are listening to you by turning their head and look at you when you do the quick tug and release on the leash. Use your verbal command, tell your dog what you want them to do. That quick movement of your fingers in a tug and release action on the leash grabs their attention very quickly and they will turn their head or give an ear in the direction of your voice; showing you that they are listening to you as you are speaking your commands. The key to your success is being consistent in your actions.
