To become a veterinarian requires years of study, including obtaining a Doctor of Veterinary Medicine degree from an accredited veterinary college. The career involves caring for a wide range of animals through activities like physical examinations, diagnostic testing, surgery, and educating pet owners. Veterinarians work in various settings like clinics, hospitals, zoos, laboratories, and farms.
