Anny sat in their backyard(后院), thinking. She was trying to think of a way to earn money during the summer vacation. Suddenly, she had an idea! Her parents paid her to walk their dog every day. Maybe other people would pay her to walk their dogs.
Anny went to many houses and asked the people if she could exercise their pets. Some of the people didn't have a dog. Others wanted to walk their own pets themselves, but five people did hire（雇用） Anny. She was delighted.
Every morning that summer she walked the dogs. By the end of the vacation, Anny had saved eighty dollars.
