I don't have any idea!

No.
Dogs lick their mouths as a way to communicate and show their emotions. It can indicate feelings of stress, anxiety, or anticipation. Licking their mouths can also be a way for dogs to clean themselves or show submission to a more dominant dog.
Dogs' mouths are not necessarily cleaner than humans' mouths; this is a common misconception. While dogs have certain enzymes in their saliva that can help fight off some bacteria, they also carry bacteria specific to their species that can be harmful to humans. Additionally, dogs do not practice good dental hygiene like humans do, which can contribute to the buildup of bacteria in their mouths.

Wrinkly.
Actually, no. Cats also have cleaner mouths than humans, and they may possibly have cleaner mouths than dogs because their saliva destroys germs better than dog's saliva does. No dogs mouths are cleaner
It is possible but not likely to happen
