How long does the average person stay a veterinarian?

Minimum is 7 years. You need to take the required undergraduate courses which take 3 years, but most prefer to get their bachelors before applying. It took me 5 years (double major, double minor). Vet school itself, if you are able to get in, is 4 years. Once you are done, you will have a doctorate of veterinary medicine. About $ 150 000.
