Huskies love the snow. It's instinctual. Like the wolves they are so closely related to, the husky knows to dig into the snow for insulation and warmth in the cold, cold winter.
Finding himself in a frigid scene without a shirt, the Wuffy attempts to den up for warmth. Or maybe he's just screwing around. Huskies have been known to do that instinctually, too.
Note: I've also fixed some errors in the Wuffy with Laptop pic, so check it out!
