I think your best bet is going to be to contact each of your schools. All of those schools are pretty big into research, so they must have lab animal vets on campus. You could try looking on their web sites or calling the dean's office to find out who teaches the vet school's lab animal medicine courses. Contact those faculty and ask them about opportunities. What lecture and lab courses are offered? Do they offer lab animal clinical rotations? What range of species do they have at the school? What about employment opportunities or "treatment crew" positions for vet students?
If the vet school doesn't offer any lab animal medicine courses, well, that says something right there. But still those schools all have research going on, so you could try contacting the campus veterinarian (you'll probably have better luck doing this through the vet school dean's office, contact info for lab animal vets is usually pretty protected for obvious reasons). Ask whether you'd be able to set up a clinical rotation at their lab animal facility, and try to gauge how much mentorship you could expect to get from the lab animal vets if lab animals aren't covered in the formal curriculum. If it's a tracking school and there's no lab animal or research track, then make sure they have an "independent" track you could tailor to meet your interests.
