Running two miles on the playground isn’t a fun thing to do for most students. But students in Miss Brown’s class at Mark Twain School in the USA gladly put on their running shoes. They wanted to raise money to help a dog in need.

Miss Brown told her students about Peter, a dog who had a hard start in life. At less than a year old, Peter’s owners found out that he was not healthy. Something was wrong with his body. Medicine could help but it was very expensive. For Peter to have a better life, he needed surgery (外科手术). But his owners couldn’t afford that. Finally, they had to leave Peter at the animal hospital.

“I love dogs and when I hear about Peter, I felt so sad for him,” says student Tony.

Miss Brown’s class decided to hold a Jog-a-Thon to raise money for Peter’s surgery.

“At first I felt like the Jog-a-Thon was just to get us to exercise,” says Mike “but then I wanted to help this dog.”

“I just wanted to make a difference in Peter’s life,” adds student Chance Wood.

News of the Jog-a-Thon spread throughout the school. Before long, five other classes also took part in the event. “I started receiving money from all kinds of people in our school community,” says Miss Brown. “We raised $3,180.64 in all.”
