I’m not in vet school, but the 4th yr student doing an internship at the clinic I work at had thousands of hours of SA general practice experience and then around 100 of LA experience; however, a vet I know that graduated not too long ago just had small animal experience. It really seems to vary.
I am planning on getting at least 100 hours of LA veterinary experience, but I already have a ton (over 500) or small animal experience as a incoming undergrad freshman. There is only one large animal vet by me, but he was hard to find. I had to ask around a ton, so don’t give up! Another recommendation is contact business-based farms by you and see if you can volunteer there. They always have veterinarians check in periodically especially if they are larger farms, so you can add that to vet experience when the vet is there as well as animal experiences, which is what I am sort of doing in college cause my college has no LA vets by it, just farms.
Hope this helps...
