The Occupational Outlook Handbook has some great information on becoming a veterinarian. I highly recommend checking it out! https://www.bls.gov/ooh/healthcare/veterinarians.htm
To become one, you need to complete a 4-year undergraduate degree followed by generally 4-years in a doctoral program to get a DMV or VMD. I recommend reaching out to some veterinarians local to your area to hear from them about their experiences, education, and what their day-to-day work looks like.
