No. A dog should not be able to break off larger pieces of any Nylabone Non-Edible Chew. Nylabones NON-EDIBLE CHEW PRODUCTS are made with plastic, rubber, or nylon. They are NOT intended for consumption. During normal chewing, tiny bristle-like projections are raised that help clean teeth. If these tiny pieces (no larger than a small grain of rice) are ingested, they should pass through. If you think that your dog swallowed a large piece of a Non-Edible Chew, take the chew away and contact your vet for advice.
