I think my favorite parts are where Bailey is charging through the snow, but all you see is the collapsing tunnel. It reminds me of all those Bugs Bunny cartoons where all you see is the mound of the tunnel as Bugs is moving.
I also love how well they synced the video to the music. And, the part where the camera is panning for him .... and panning .... and the suddenly we see that little dot of a head poke back up.
I have never seen one dog have quite so much fun in the snow.
