When pets get sick(有病的), you can usually take them to an animal doctor or an animal hospital. Sometimes animals are so ill or hurt that you shouldn't move them. That's why Doctor Bird, a veterinarian, has a traveling hospital. Doctor Bird drives his hospital, which is really a van, to the animals.

Doctor Bird has run the hospital for over 10 years, and he has saved the lives of many pets. The van has an operation table, medicines(药) and everything else he needs to treat animals. Doctor Bird says that there will soon be many more traveling hospitals to help sick or injured(受伤的) animals.
