     Hi! I'm Harry. Life used to be kind of difficult for me. The muscles (肌肉) in my arms and legs are weak.

I have to be in a wheelchair all day. I can't use my legs at all, and I'm not too great with my hands. If I drop

something it stays dropped until someone picks it up for me. I can't open doors or switch lights on and off.

Carrying everything I need for school is a problem too.

    Now things are easier. I have a helping hand. Pete is a golden dog that has been trained to help kids like me.

Pete was at dog training school for two years to learn how to do different tasks. I had to be trained too. I had

to learn how to give Pete instructions and how to take care of him. 

    When Pete is working he doesn't play around. My friends know they are not to pet him or call him when

he is working. He can pull my wheelchair and pick up things I drop. Pete carries my books and lunch on his

back. He pushes the button on the school lift and opens some kinds of doors. He even knows how to switch

lights on.

    But best of all, Pete is here when I need a friend.
