A veterinarian, or vet for short, is an animal doctor. Vets help sick and injured animals get better. Vets can do almost anything a regular doctor can do.

Some vets work in zoos with exotic animals like lions and elephants. Working as a vet with large animals or wild animals can be very dangerous.
