Once upon a time, there was a wise old dog named Spot. Spot lived in a small house with a big yard. Every day, Spot would run and play in the yard. He loved to chase birds and dig holes.
One day, a little boy named Tim came to the yard. He saw Spot and said, "Hi, Spot! Can I play with you?" Spot was happy to have a friend and they played together all day. They ran and jumped and had lots of fun.
As the day went on, it was time for Tim to go home. Spot didn't want Tim to leave, so he didn't close the gate to the yard. When Tim left, Spot went to sleep. In the night, a big mean dog came into the yard. The big dog saw the open gate and went in. The big dog chased Spot and hurt him. Spot was very sad and wished he had closed the gate.
