When I first saw the dog Lucy, she was about the size of a little dog. I thought she was(small) dog in the world. She was so cute.
However, she was very naughty(淘气的) dog. One night, she ate our socks and (break) our shoes. My mom did read some books about dogs, but we were not prepared for the naughty dog. We were very angry and we shouted to her (loud), but it didn't work.
So we decided (take) her to the dog school. We believed that she could learn how to be a man's best friend there. After a few (month), we were surprised that Lucy could even help us do some small things.
Now, Lucy is already 10 years old. Though she is a little old, she can still help us a lot. For example, I say "socks", she will run quickly to get my socks. Thanks to the dog school, it has made a big (different) to Lily.
