Dile

Dile: noun. A dile is a facial expression common to dogs that appears to be equivalent to smiling in humans, but includes characteristics humans usually lack. For example, when diling, a dog usually sticks its tongue out, pants and even wags its tail, while humans don´t do any (or at least most) of these when smiling. Also, a diling dog is the same thing as a laughing dog, as dogs make very little sounds (if any) when they are somehow amused. The most famous example of a constantly diling dog is the popular internet meme called doge, though many find its smile a bit too creepy to be called a real dile. For future reference, although diling is most commonly associated with dogs, it is also frequently observed in dolphins and to a respectively lesser degree in ducks, drivers, dancers, diggers, dragons, doctors, dinosaurs and diprotodons.
