Recycle in Style! The Earthstyle line webbing is made from RECYCLED PLASTIC BOTTLES! The No-Pull Harness features a patented control loop on the back of the harness which tightens gently around your dog’s chest to discourage pulling behavior and makes walking your dog an easy, more enjoyable experience for both of you. It also features a structural connection ring on the front of the harness. Connecting to this ring is optional, but recommended, as it allows you to attach to the front and back of the harness simultaneously.
