I am doing a project about are dogs mouths cleaner than humans for the science fair. And I just need to know from people which mouth they think is cleaner, a dogs or a humans?

it is really hard to say maybe you shouldtake yourself and a dog and get tested

dogs, humans make out too much

i know it's been said that dogs mouths are cleaner, but i don't see how. most of the dogs i've owned eat poop.

I have always heard that a dogs mouth is cleaner then a humans...im not sure why though...But i do know it has something to do with the bacteria in the dogs mouth compared to a humans.

depends on the human and the dog, but I do believe a dog's is actually suppose to be cleaner, I like to think mine are though.

I dont think it's cleaner because dog lick their asss, and private part! and they eat shitt

Believe it or not human saliva is the worst for carrying infections. Yeah ... we all know what stuff dogs eat but they have an enzyme in their saliva that kills bacteria. Any time I've had a cut or abrasion, I let a dog lick it clean (if there's one around) and it heals up clean and fast. I've talked with a number of other folks who've experimented with this with their dogs and they agree. Mind you, their dogs are healthy.

Humans are cleaner, by far! Humans get regular teeth brushings... Dogs eat their own poop and, sometimes, vomit. You do the math there.

i have herd that it is a dogs mouth...how i dont dont because to me it doesnt make and since

Well this is what I have heard before and I know think this too (even though the answer is wierd), a dog's mouth is cleaner. Also as the Esther said, on MythBusters on Discovery channel, they had an episode about it.

From what Ive learned a dogs mouth is cleaner...It doesnt carry as much bacteria as our mouths do...

dogs mouth are alot cleaner than ours..even though they put things in there mouths.

Dogs, our mouths have more bacteria. My dog will lick anything, what does that say about us???

A dog's mouth is cleaner.Good luck with your project.
