Once upon a time, there was a doctor. The doctor was very nice. He helped people when they were sick. One day, a naughty dog came to the doctor's place. The dog was making a big mess. The doctor was not happy.
The doctor wanted to make the naughty dog nice. He gave the dog a yummy treat. The dog liked the treat. The doctor said, "You need to be nice, not naughty." The dog wagged its tail and stopped being naughty.
Everyone saw the doctor help the naughty dog. They were very happy. They all clapped their hands. They said, "Yay! The doctor is so good!" The doctor and the dog smiled. They were happy too.
