Once upon a time, there was a little dog named Spot. Spot had soft fur. He was a troubled dog because he could not catch his tail. Spot would try and try, but his tail was too fast.
One day, Spot met a big dog named Max. Max saw Spot try to catch his tail. Max said, "Spot, I can help you. Just try harder and you will catch your tail." Spot tried harder, but still could not catch his tail.
Spot felt sad, but Max had an idea. Max said, "Spot, let's play catch with a ball instead." Spot and Max played with the ball and had lots of fun. Spot forgot about his tail and was not troubled anymore.
