You will want to look up some websites of schools offering the Doctor of Veterinary Medicine degree and find out from them what a pre-veterinary curriculum consists of. There are only 27 schools in the entire United States offering the DVM degree. So far as I know, none of the Arizona schools offers the DVM; however, within a one-state radius of Arizona, you do have University of California Davis and Colorado State University offering the DVM. Once you’ve found out from them what a pre-vet curriculum is, look at what schools offer that. You’ve got a long journey cut out for you, as you’ll have four years for your bachelor’s followed by another four years for your DVM. Good luck to you.

arizona does not have a vet school. Check out avma.org under the education section and they will give you a list of vet schools. I think there are some schools in arizona that have a vet science department so you could do undergrad there but no DVM program. (i think aavmc.org has a list of schools with vet science departments)
