Dog vs. Rock vs. Gravity

Either this dog is having a hard time or he found a way to play fetch with himself! This canine sisyphus keeps trying to put his rock down but it continuously rolls down the hill. Gravity keeps pushing the rock down the smooth surface. After a while, the dog learns he's got to move the rock further up on the sidewalk. Animals have a keen sense of learning and pick up from their mistakes. Dog versus rock versus gravity, Dog wins!
