How Clean is a Dog's Mouth?

Good article on the Pet PlaceIs a dog's mouth cleaner then a human's?

Apparently not. Dog's mouths are filled with all kinds of bacteria, depending of course upon what the dog had in its mouth recently. When you consider that dogs use their mouths much like people use their hands, the bacteria counts in their mouths can be quite high. Suppose your dog has been eating fecal material, taste testing a dead animal, licking your shoe, or simply chewing on a stick that has been decomposing on the ground-your dog could have a nice selection of harmful bacteria cultivating within the mouth.
