If so, you may want to think twice the next time you kiss Fido.
It turns out "dog breath" does exist--kind of. A study has concluded that people who kiss their dog on the mouth could wind up with gum disease. Japanese researchers found a majority of the same bacteria that was in a dog's mouth, was in their owner's mouth. Yikes. Some vets are saying this isn't a proven, "conclusive" study, but you can still file it under "good to know."
Will this make you ease up on the puppy love? I don't really let my dogs lick my face (and I don't kiss them on the mouth). I kiss the top of their heads all the time though!
