We all get licks of love from our dogs, but do you ever let you dog kiss you? We've all heard that dogs' mouths are clean.
It turns out you might want to think twice before you do that again. As an experiment, dog saliva samples from Florida were sent to a university lab to be tested.
Researchers say there's quite a bit of bacteria growing in dogs' mouths, including some linked to pneumonia, plaque and STDs. One doctor reminds owners to think about where a dog tends to link and where they may have just licked before giving you a kiss.
However, doctors say the bacteria doesn't stay in a dog's mouth for long. Any ingested organisms are gone if a few minutes. In the end, researchers say testing didn't find anything out of the ordinary.
