This harness for dogs is specially designed in collaboration with professionals. The NO-Pull (anti-pull) harness is made from premium materials and is specifically designed to distribute pressure over the dog's body for optimal comfort. The harness is adjustable at 4 points for the perfect fit. By using material that is normally used for rescue operations or mountaineering, the quality of the harness is guaranteed. There are 2 metal rings where you can easily attach your dog leash. The top ring is for dogs that do not pull or barely pull, and for pulling dogs, you can use the ring on the chest side.
