To become a veterinarian, a candidate must earn a Doctor of Veterinary Medicine degree from an accredited college or university. Many veterinary school graduates go on to complete 1-year, unpaid internships under supervision. As post-graduate students, veterinarians can also complete 3-4 year residencies if they wish to become board certified in a specialty area of veterinary medicine. A bachelor's degree isn't necessarily required in order to enter a veterinary program, but applicants must have a designated number of undergraduate credit hours completed. However, according to the U.S. Bureau of Labor Statistics, most applicants hold a bachelor's degree. Many schools also look for candidates who have experience working or volunteering in veterinary clinics or similar settings.
