I liked the story about the happy dog. The dog is very cute and playful. He has a big smile and likes to run in the green grass. The dog is friendly with everyone he meets, wagging his tail and jumping with joy. My favorite part is when the dog finds a shiny ball in the tall grass. He plays with the ball, tossing it into the air and catching it with his mouth. It was a fun and exciting story, and it made me happy.
