In Tibetan culture, people greet each other by sticking out their tongues. It's also used to show respect. One can't help but think that this fella will get along great there.

Holy Cow, look at that tongue! The Tibetan's tongue sticking out culture derives from the belief that a person with a black tongue is wicked. If that's so, then this dog must be the most kind hearted creature on earth! He looks happy too :)
