Petmate's Booda Fresh N Floss Rope Toy keeps dogs' teeth and gums healthy while providing long-lasting tugging fun. Featuring mint-scented floss and baking soda, the tug toy fights plaque and controls tartar. Dogs stay happy and healthy with the non-invasive and non-irritating fibers that gently clean teeth and gums. The wax-coated nylon and durable all-natural cotton fibers hold up to games of tug-of-war and last longer without fraying. The three knots on the rope toy allow for better grip during tug-of-war. The Fresh N Floss toy is available in medium, large, and extra large to accommodate all types of dogs.
