They say smiling helps lift your mood and could even increase your lifespan. If that's really the case, then this labrador is guaranteed to live a long and happy life!
When the video begins, the camera is zoomed in on the labrador, who is lying on the floor with a depressed look on his face. After a few seconds, though, for one reason or another, his face lights up.
Yours will too after you see this clip!
