Great sequence.
I admire the fury of a small animal protecting its young. I'm pretty sure the dog was in "play mode" (which can easily be lethal to a squirrel), but still, to take on a gigantic black monster with huge fangs that outweighs you by maybe 50 to 1, is no mean feat in anyone's language (or spelling).
Oh and uncooked it would be squirrel sashimi. "Sushi" refers specifically to fish. Sashimi is any raw meat. [/fact nazi]
