Is A Dog's Mouth Cleaner Than A Human's?

No, a dog's mouth is not cleaner than a human's mouth. If this were true humans would be trying to figure out why and how humans can have very clean mouths. Many people can become ill after being bitten by a dog. It has been known for a long time that dog bites can cause diseases much more easily than other animals. Also, dogs use their mouths to clean themselves, so their tongue would have many germs on it. It is true though that humans mouths are the dirtiest places in their body dogs mouths are still not as clean. -John Baskin
