David Springer,
If you have a fact, you might care to produce it. Otherwise, as you so elegantly put it, FAIL.
In relation to sled dogs burying themselves in snow to stay warm at night, I believe you may be slightly mistaken. If you have information to show that sled dogs do any more than pack the snow down, using the same motion as any other dog, you might care to produce it.
Sled dogs curl into a ball, so to speak. They have a top coat and an undercoat, good enough to stop moisture reaching the skin even when swimming. Well insulated. Of course, dogs lack sweat glands over their skin, so retain internally generated body heat far better than humans.
This is why sled dogs can manage to remain asleep through blizzards, in some cases becoming covered with snow. The dog is smart enough to ensure it can still breathe, of course.
People can build snow caves to get out of the wind, and sleep nicely in their down filled sleeping bags. Or you can use a tent, unlike most dogs.
Have you any more irrelevant, misleading and incorrect or incomplete analogies or bon mots to gently toss my way?
On this occasion, I reluctantly award you a FAIL.
