Everyone either thinks or comes right out and says the same thing when they see a dog lick someone's face, "Do you know where their tongue has been?"

But the next time you get grossed out, you might want to hold off on your disgust.

Researchers at the University of Arizona are doing a study to see if a dog's saliva can help with allergy symptoms.

Allergies are more common than ever now. Experts believe it is because we are so sanitary and not being exposed to as much good bacteria as we used to be. Think about it, when was the last time you drank water out of the faucet?

Things like that have proven to strengthen our immune system. Studies have shown that kids that grow up with dogs tend to have fewer allergies. Their thinking is that dogs pick up bacteria by licking things and rolling around in stuff. This helps kids build resistance.(ABCNews)

Kids, this is the perfect argument to get your parents on board to getting a dog! The next time they say, "NO", show them this article.
