Note: I heard rawhide chews are bad for dogs and the rescue I volunteer for does not give them to dogs. I found this from DiscussDogs.com.
Real marrow bones are nutritious, good for cleaning teeth, and will keep your dog occupied for hours. Tartar reducing dog biscuits are available containing chlorophyll which neutralizes odors and keeps their breath fresh. You can also purchase special chew toys designed to clean your dog’s teeth. These can be used with dog toothpaste to clean even better. For the moderate chewer, these provide safe entertainment as well. Special chew toys and dental chews can be purchased for the more aggressive chewer who can easily tear up their normal toys and choke on them. Increase their stimulation by finding toys that are designed to contain treats which your dog can to try and get out of the toy.
