Lili the dog's owner recently uploaded a clip of her pet to TikTok and the little animal's unique "smile" brought smiles to countless others!

The short recording quickly made waves on the social media platform, as the video shows the mini Dachshund vibing in a tropical locale.

Apparently sitting on a balcony, Lili is grinning because of the good time, her little teeth peeking out of her snout in a cute but also very funny sight!

First she looks into the distance, then she looks straight into the camera with her million-dollar smile.
