Patented "Chew-clean" grooves effectively squeegee clean dog's teeth and gums as they chew. The large and extra large sizes are bone shaped with hollow interiors designed for holding treats. As dogs try to remove the treats, their teeth and gums are effectively cleaned by the grooves (which can be used with dog toothpaste). The medium and small sizes have Kong's exclusive diamond braid cotton floss rope which effectively removes food debris... Reduces plaque and tartar build up. All of the models uphold Kong's legendary strength and performance - even the unique bounce!
