Jolly Pets' Knot-N-Chew dog toys offer a chewing challenge and tug toy all in one. Tightly woven rope fibers floss dog's teeth as they chew and are more durable than traditional rope braid dog toys. This make the Knot-N-Chew dog toy perfect for teething puppies and strong chewers. Ideal for indoor or outdoor use, the Knot-N-Chew encourages interactive and solo play, and relieves pent up energy. Proudly offered by Jolly Pets. Jolly Pets is proud to support organizations nationwide that provide dog toys to dogs in shelters- we believe all dogs should be Jolly
