The Pet (1921) ***

Based on the famous Winsor McCay's comic strip "Dreams Of The Rarebit Fiend", this cartoon tells a story of a little puppy that grows into a monstruously huge dog. It devours furniture, home appliences, even brick walls. Gentle attempts to destroy it (like rat poison) prove fruitless. Only the heavy artillery and warplanes manage to stop the monster. Slow moving, but quite memorable and possibly an inspiration for "King Kong" and the Japanese Godzilla movies.
