You are Buying a Brand New PetSafe Easy Walk Padded Dog Harness in Teal Gray Size Medium.... This no-pull harness was created by a veterinary behaviorist in 2004 and is paw-fect for dogs who pull during walks. The patented martingale loop design safely stops pulling by placing gradual pressure on your furry friend's shoulders. Unlike collars, this harness rests across your dog's chest, so you don't have to worry about him gagging or choking. The leash attachment on the front lets you direct your dog during walks. Designed with quick-snap shoulder and belly straps for easy fitting. The different color belly strap makes the harness easy to put on. With less coverage than many other harnesses, this breathable harness keeps your canine companion cool during your walks.
