Chewing on bones (rawhide) helps dogs of all ages in a number of ways. In using the term 'bones' we do not mean bones leftover from a roast, etc., which may cause digestive problems and which are too abrasive and can wear down the teeth. Instead, we mean chew bones specifically designed for dogs.  Chewing on dog chew bones or hard toys helps scrape away plaque, which can cause bad breath and a number of potentially serious dental problems.
