Beaver Trouble

Two beavers, working harder than beavers, are cutting down trees in order to build a dam when they notice cords of wood piled next to a dog-house. They start hauling it off, as a labor-saving device, but the guard-dog objects and starts chasing them. They easily avoid his futile attempts to catch them and, to add insult to injury, they even dismantle the dog-house. When winter comes and the first snow, the dog, his house destroyed by the beavers, is out in the cold. (imdb)
