SmartBones Dental Chews are made with real chicken and provide the chewing exercise of a rawhide without the risks. Veterinarians have been apprehensive in endorsing rawhide because of potential choking hazards and concerns over digestibility. However, SmartBones are 99% digestible and 100% delicious. Tests show 9 out of 10 dogs prefer SmartBones over leading rawhide chews and these chews are fortified with vitamins and minerals. Dental flavor contains chlorophyll and parsley seed oil for additional dental benefits.
