Adrian Schaffner's dog Sintha refuses to leave his side, even when he's hitting the slopes.

This video is what's great about the Swiss. While the rest of the world was getting involved in wars, they were biding their time, building quality timepieces and teaching their dogs to participate in winter sports. Sintha here is a classic Swiss Army Dog.

The video's uploader, Zurich-based Adrian Schaffner, says that Sintha was injured at just five weeks old and had trouble walking, which is when she got used to riding on people's shoulders. Now that she's all better, this makes her the fastest dog on the mountain.
