The Swell Ruff Leash 2.0 is a shock absorbing dog leash that has a spring that's designed to absorb the impact of your dog pulling during walks. This leash has a two-toned blue design for a relaxed vibe and has a soft, cushioned neoprene handle. The super hook has a screw lock for extra safety.  Available in 2 sizes, it's no wonder that the Ruff leash was voted the best dog leash in the world by Pet Product News International.
