Is a Dog's Mouth Cleaner than a Human's? - I have a problem with people who say "a dog's mouth is cleaner than a human's." I have asked for facts from these people to back up their statements but no one has been able to provide them to me.

I believe that dogs and humans have similar enzymes for breaking down food, and I know that my dog licks herself in places I don't, and she always has "doggie breath."

I don't think it's possible for a dog's mouth to be cleaner, unless dogs have some super-secret enzyme that we don't.

    The way I heard it when I was a kid was that a dog's mouth is actually "sterile."
    I believed what I was told at the time in spite of the contradictory evidence at hand — namely that people often become quite ill and even die after being bitten by a dog. If a dog's mouth is sterile, how could it transmit rabies, tetanus, pasteurella or any of the other types of infection associated with dog bites?
    So, where did the notion that a dog's mouth is cleaner than a human's come from? Doctors, evidently. It has long been noted in the medical literature that human bites are more likely to become infected than those of other mammals, including dogs. Statistics to that effect were published in journals and repeated by medical professionals, and folk wisdom took off from there.

    Here's the deal.  My 6th grade son is in the process of finishing this Science Fair Project.   He did "Whose Mouth is Cleaner?  A Dog's, A Cat's or a Human's."  We ordered sterile Petri dishes and did a Control, then swabbed our cat's mouth, a dog's mouth and then a family member's mouth.  The first Petri dish that we used for the human, did not grow ANYTHING, but the person had just brushed their teeth, tonque and also used anti-bacterial mouthwash.  We decided to try again just mid-day.  The person brushed their teeth that morning like normal and then sometime that afternoon, we swabbed them again.  That Petri dish did show a little bacteria, but not much at all.  The cat's was the worst, but the dog's was a VERY close second.  It was disgusting.  Even though we thought we had them sealed very well, they were extremely stinky. We ended up having to take photos of them and then get rid of them because I was afraid that we would have to call disease control if we waited much longer. ;-)  

    Anyway, I am just curious as to where to get research other than the experiment we did that shows that a dog's mouth really ISN'T cleaner, because now, we know it is not!
