One day, a little girl named Lucy was playing in her room. She was playing with her dolls and having fun. Suddenly, Lucy noticed that her mom was worried. Her mom was looking at the telephone and talking to someone.
"Mom, why are you worried?" Lucy asked. Her mom said, "I am talking to Grandma on the telephone. She is not feeling well and needs help."
Just then, there was a knock on the door. Lucy's mom opened it, and there was a big, friendly dog! The dog came inside and wagged its tail. Lucy's mom smiled and said, "This dog is a helper dog. He will go to Grandma's house and make her feel better."
Lucy was happy that the helper dog would take care of her grandma. She knew that her grandma would be okay with the dog's help. And the worried look on her mom's face went away.
