Came across this article this morning, about some lost hikers who made it off Mount Hood alive. In part, their luck was due to the lab mix hiking with them, Velvet. Quoth the article:
"The dog probably saved their lives" by lying across them during the cold night, said Erik Brom, a member of the Portland Mountain Rescue team. As the group started out on Saturday, the weather was clear and Velvet was leading the way, Liston said. "She looked back every once in awhile to make sure we were OK."
Gotta love that.
