Recommended by vets, the Puzzle Bone is designed with moving 'puzzle' parts that react to your dog's movement which further adds to his chewing enjoyment. During normal chewing small bristle-like projections will be raised which help clean teeth and massage gums. This product is not consumable but any small shavings (no bigger than a grain of rice should pass through). Replace when knuckles are worn down. Please read enclosed Guidelines for Use before using.
