I have a chihuahua mix, who has a thick chest and neck, but the rest of his body is skinny. It's hard to find harnesses that fit him properly, and he can wiggle himself out of any collar and harness I've ever tried. Escape artist of the decade! But the no pull harness has been great! He cannot make his way out of it, and it's comfortable on his thick little body. He is not a fan of the connection at the front, but he is getting used to it. The leash is perfect! I absolutely love how comfortable it is on my hand, and now my kiddo can help take our puppy on walks.
We love it
