This chew is formed from an edible, digestible dough built around rice flour, vegetable glycerin, corn starch and natural chicken flavor, with no plastics or polymers in the recipe. Raised dental ridges run along the surface and are designed to help scrub the teeth and gums as a dog gnaws, licks or chews the treat. It is made in the USA and is free of wheat and soy. The chew can be handed to a dog as a standalone snack or inserted into a compatible Starmark Everlasting toy, such as a treat ball or bento ball, to turn a chewing session into a longer mental and physical challenge. It is intended for intermittent or supplemental feeding rather than as a complete diet, and dogs should be supervised while chewing since no chew product is fully indestructible.
