If a dog really is man's best friend, then you'd think it'd be more enthusiastic about celebrating his birthday.

In this video, a group of people are singing 'Happy Birthday!' at a party when the camera pans out to find a pooch sitting all by his lonesome. It's sad and pathetic, but in the cutest "awwww" way you can imagine.

Maybe he's just really sad because the person who took this shot it vertically.
