High school students interested in becoming veterinarians should seek part-time or volunteer work on farms; in small-animal clinics, pet shops, animal shelters, or research laboratories. Extracurricular activities, such as 4-H, are suitable ways to learn about the care of animals. This is essential because numerous veterinary schools have established experience with animals as a criterion for admission to their programs. Many veterinarians advise those determined to enter the field to start applying to vet school in the first year of college or university, because it is not uncommon for students to get rejected one or more times before being accepted.
