Well, i used that trick with my old outside dog..... Hung a lightbulb in her doghouse, and sealed the door with an old truck innertube with a slit in it. She never froze, or even got too cold. It was the funniest thing ever to see her pop her head out and look around after a big overnight snowstorm, and then pop back in to a long winters nap!! :thumbsup::thumbsup:
