The old wives’ tale about a dog’s mouth being cleaner than a person’s is totally untrue. Dogs spend a lot of time doing some pretty gross stuff: they lick themselves, sniff the rump of other dogs, and eat some pretty nefarious things, such as rotting animal carcasses and the feces of other animals. Letting one’s pooch lick them, much less in the face, can lead to a variety of skin issues, infections and even parasitic invasions.

• A ringworm infection is one of the easiest diseases for your dog to pass onto you from smooching.
• Are you going to catch a disease from your dog that leaves you with one foot and disfigured hands? Probably not. But are you going to take the chance?
