new, never used. The SENSE-ible Harness Gently Stops Dogs From Pulling. The SENSE-ible Harness is a front-leash attachment harness - very different from the "sled dog" style of most harnesses on the market. The leash attaches to a ring on the chest, so you can provide more accurate cues to your dog as to the direction that you want to go. It reduces pulling and often enables a smoother, more enjoyable walk for both dog and human. Quality hardware and construction. Ny curved side-release buckle and belt loops. Nickel-plated metal slide adjusters and welded o-rings. Measure your dog's girth using a tape measure. Measure around the body (the rib cage) behind the front legs.
