The Canyon 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. The handle is soft and cushioned with neoprene and the leash is made with a blend of natural flax fibers and polyester. The super hook has a screw lock that can be locked by rotating it 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.
