This is a set of a leash and harness recommended for puppies making their walking debut. Both the harness and leash are made of soft, lightweight cotton-like material, so they are unlikely to put a strain on the body even if the puppy pulls. The back of the harness is mesh. I hand-washed it before listing, but there are some stains that I couldn't remove.
