Mammoth Rope Flossy Chews. These Rope Dog Toys are chew and fetch dog toys made entirely of braided rope. The rope used is composed of a flossy material that scrubs away plaque as your dog chews. As the rope is chewed more, flossy rope strands will stimulate your dogs gums to improve overall dental health. Great for fetching, dog tug-o-war, and good old-fashioned chewing.
