It wasn't a veterinary internship, but a keeper internship in the Jungle of the Apes. I did see 2 veterinary procedures (maybe 6 hours total) - an orangutan had airsacculitis and a chimpanzee had a peritonitis and was euthanized, all of which I was present for. I went to Wash U, which is right across the street from the zoo. The other girl I interned with was from U of I, I believe. It was an amazing experience for me, but I have to be totally candid - I didn't enjoy the keepers and wasn't able to get a recommendation from them. I didn't even ask. They were very unprofessional (they chatted and gossipped a lot - I spoke up and was told I wasn't a team player. I actually wrote about this experience on my Cornell app) and weren't interested in teaching us about husbandry. So, it was a learning experience in many ways. It is competitive, but worst case they say no. Just go for it.
