Are you considering going for a DVM and becoming a veterinarian?
If so, then definitely budget for a full 8 years of university and go for an affordable bachelor’s degree. Saving money is important. Getting a DVM is a long road. It requires a lot of determination and a lot of effort over a long time period. While being a veterinarian can be a rewarding job, it is a lot of work and does not pay well enough to pay off the cost of the DVM program if you need to take even half of it as loans.
My older daughter got her DVM this past May and is working as a vet. She loves it. She has consistently reported that most of the students in her DVM program were taking on way too much debt. At her graduation we never talked about it because we did not want to make other students feel bad during what was a very joyous and very positive celebration.
DVM students come from a very wide range of undergraduate schools. Anything on your list, including any of the UCs, can prepare you well. Students in highly ranked DVM programs come from all over the place. Getting quite a bit of veterinary-related experience would be very helpful, and might be easier to come across in rural areas particularly if you want large animal experience.
Regarding chancing you, you are a very strong student. You are competitive for Stanford, but so are something like 80% of applicants (this number is taken from an article in the Stanford alumni magazine from a number of years ago, but I doubt that this has changed much over the years).
I expect that you will get some acceptances from some of your reach schools. Whether they are worth the cost compared to your in-state public schools is a tough question, and may depend upon whether you want to keep open the option of someday applying to an expensive graduate program (such as a DVM, or MD, or …).
