Enjoy hands-free control when you and your dog hit the pavement. Versatile, flexible and comfortable, the Stunt Runner™ & Go Dog Glo™ Harness were created specifically for—and are loved by—runners. The flexible connector piece that attaches you and your dog stretches from 37" to 50" to easily absorb slight variations in stride, and clips to an adjustable waist belt with a sliding D-Ring to keep your running partner in just the right spot. All in all, a simple, lightweight design that won't slow you down.
