Many people have the wrong idea about pigs. Pigs are actually very clean animals. On farms, they live in
dirty places. So, they become very dirty. In the wild, pigs keep very clean.
They are also really smart. They may be smarter than dogs. So, pigs can learn things from people. Pigs
are very friendly animals. Some people raise (喂养) them as pets. Of course, people keep the small kind, not
the big kind. Small pigs are very cute. And they don't break things in the house. Big pigs usually live outside
on farms, not in people's houses.
