Dakota has the worst teeth I have ever seen. His breath is terrible. Taking him in for a dental is out of the question since he is 9 years old and has medical problems and a surgery may be too much for him. They are past the point where brushing will help and quite frankly, I cant brush his teeth because they are so disgusting and he drools. I do not give my dogs raw hide. However, when I used to Dakota was not good at breaking off small pieces. He would try to swallow big pieces. I know some people recommend other things for chewing, does anybody have any suggestions? Any toys with cleaning ability will not be beneficial since he doesn't like to play.
