The TTP ring improves the weakness of Y/T-shaped harnesses by protecting armpit. And it helps to be fit for dogs who have slim waist and broad chest, reducing discomfort. It is designed for easy control with minimal power from the dog owner and tightens around the chest when pulled,minimizing twisting or rotating of the harness. The webbing straps are diagonally positioned to protect the armpit. For breeds with a larger chest and a slender waist, the webbing strap around the belly prevents the harness from slipping off.
