Do you need any proof that graduated 12th grade to be a animal doctor?

Yes, you definitely need proof of graduating high school to be an animal doctor. In the United States, the minimum educational requirement is a bachelor's degree from an accredited college or university. Some schools also require applicants to complete a master's degree or obtain their Doctor of Veterinary Medicine (DVM).

In order to be admitted to veterinary school, you will need to submit transcripts showing that you have successfully completed all the required courses. You will also need to take the GRE (Graduate Record Examinations) and achieve a satisfactory score.

Once you have been accepted into veterinary school, you will need to complete four years of study. This coursework will cover a variety of topics, including animal anatomy, physiology, nutrition, and disease. You will also need to complete a period of clinical experience working under the supervision of a licensed veterinarian.

Upon successful completion of veterinary school, you will be awarded your DVM degree. This will allow you to practice as a veterinarian in the state where you have been licensed.
