When you ask what college you should go to, do you mean which vet school or what college/university should you go to prior to vet school?
To complete your requirement for entrance in to vet school you will need to attend a 4-yr college or university. This institution does not need to be a university that has a vet school.
You could start your college education at a community college and then transfer to a 4-year university/college or go straight to university/college right after high school.
What to study for your bachelors might depend on what kind of practice you want to do as a veterinarian. If you want to work with cows, poultry or horses, animal science would be a good major. If you are interest in research and lab animals (primates, rodents, fish), then maybe look for colleges with strong programs with biology, genetics, or comparative physiology. If you want to work with exotic animals or wildlife, you may want a college with a good ecology program.
The college you go to for your bachelors is not as important as the grades you get, your score on the GRE, the experiences you acquire in the field and the letters of recommendations you can get.
