SmartBones, SmartChips, and SmartSticks are everything their names suggest. They offer the hard texture and oral-health benefits of a rawhide chew - without the rawhide. Their grain-based outer shells contain a delicious mix of corn, sweet potatoes, peas and carrots. Inside, a delectable ribbon made with real dried chicken encourages your pet to keep chewing. SmartBones, SmartChips, and SmartSticks are also fortified with vitamins and minerals, so they provide more nutritive value for your pet than ordinary rawhide chews. Your dog's chewing action massages gums and cleans teeth. Highly digestible (over 99%).
