Dogs lick. That's hardly a newsflash, but what they lick may surprise you.

Take this pooch. He's super happy. Like, SUPER happy.

The tail is wagging back and forth at breakneck speed and he's busy licking away on the window, which begs the question: is he happy because he's licking the window or is he licking the window because he's happy?

You know what? We don't know and we don't care. It's just nice to watch him do his thing.
