It's three times the fun with this bone/donut/rope combo! Plus, it can help reduce stress and promote a healthy dog smile. The Canine Clean Bone/Donut/Rope is a great way for dogs to massage their gums and help remove tarter from their teeth. Dogs can tug on it, or you can toss around and play fetch with this chew toy. The rough nubbins on the dumbbell and bone help to massage your pet's gums. The rope end acts as a 'floss' for your pet's teeth. Encourages healthy play. A fantastic dental chew toy.
