Dogs Mouths Are Cleaner than Humans
It is often believed that a dog’s mouth is cleaner than that of a human. Some people believe this because a dog’s mouth doesn’t smell. However, as much as we want to think that our dogs have excellent dental hygiene, they don’t. The mouths of dogs contain bacteria just like that of humans.
But, it’s even worse in dogs because they don’t clean their teeth. Some bacteria are found in human and dog mouths, while some are exclusively from dogs. You could potentially suffer infection if your dog licks your skin, especially if there is an open cut. People should not expect excellent dental hygiene from an animal that licks its butt!
