Once upon a time, there was a loyal dog named Buddy. Buddy wore a red collar around his neck. He lived in a big house with a girl named Sue. Sue and Buddy loved to play together in the yard.
One sunny day, Sue and Buddy went to the park. They saw a big slide, and Sue said, "Buddy, let's slide down together!" Buddy was excited and wagged his tail. They climbed up and slid down the slide, laughing and having fun.
As they played, a mean cat named Tom appeared. Tom didn't like Buddy and Sue having fun. He thought of a bad plan. Tom went up the slide, and when Buddy and Sue slid down again, Tom jumped on Buddy's back. Buddy was scared and ran away, leaving his red collar behind.
Sue cried, "Buddy, come back!" But Buddy was too scared to come back. Sue could not find Buddy, and she went home sad. The mean cat Tom took Buddy's red collar and wore it, pretending to be a loyal dog like Buddy. But everyone knew Tom was not a loyal dog, and they missed Buddy very much.
