Three little dogs lived in houses made of different materials - paper, fabric, and bricks. While cooking dinner, they heard a stomping noise and saw a hungry dragon who could smell their food. The dragon demanded to enter each house, and when denied, huffed and puffed to burn down the paper and fabric houses. The dogs escaped to the brick house, which the dragon couldn't destroy. They were then safe and helped rebuild the first two houses out of bricks as well.
