Oravet Dental Hygiene Chews are a daily chew given to dogs to help clean teeth and prevent bad breath. When chewed, the ingredient delmopinol is released into the mouth, blocking bacteria to help prevent plaque, calculus and bad breath. Due to their shape, it is hard for a dog to swallow them whole, therefore they are chewed (and enjoyed) by dogs.
