Anybody ever tell you, "A dog's mouth is actually cleaner a human's" and wonder how that could be possible?  Well myth busted!

According to a new study published in the archives of Oral Biology dog owners have high rates of a type of dangerous mouth bacteria.

Japanese researchers analyzed the plaque of dog owners and dogs. They found that a higher-than-normal 16 to 30 percent of dog owners have periodontopathic bacteria, germs which make you susceptible to diseases of the teeth and mouth.

But it isn’t just humans who suffer when Fido plants a wet, sloppy kiss. Seventy percent of dogs have periodontopathic bacteria, and the researchers suspect that dogs can catch the germs from humans just as easily as humans can catch them from dogs.

So, will you be giving a second thought to letting your dog lick your face?
