The PetSafe® Easy Walk® Harness was created by a veterinary behaviorist over 15 years ago to stop light to moderate pulling. It puts pet-parents in control of the leash and is recommended by vets and trainers. The patented front clip d-ring with martingale loop reduces leash pulling by steering your dog and provides more control of your walks. The quick-snap shoulder and belly straps allow you to fit the harness in just a few minutes. Perfect-fit guarantee ensures it will fit pooches of all proportions. And, if your furry friend decides to turn the harness into a chew toy, there's a 1-year chew damage replacement policy for a minimal fee.
