I think its pretty hidden, Ive heard of as low as 97 (this was a while ago), but Id be aiming for 98+. What I will say is please advise your friend to do their homework before getting into being a Vet. It is one of those careers where outside appearances are vastly different from the reality. Being a vet in private practice (most common path), often involves being a business person. Unlike being a human doctor with steady demand and Medicare subsidisation, you really have to work hard to establish your practice and develop a steady stream of business. In tough times, people avoid the vet and unlike with Medicare, people pay vet fees up front. That is on top of the already stressful and emotionally charged nature of the job, dealing the with public who want to save their pets but will often baulk at the high cost (again, no Medicare to fall back on). It can be a very taxing profession, a far cry from being surrounded by puppies and kittens all day. I would STRONGLY advise your friend to do some practical work experience at a Vet to see the reality before going further.
I dont say this to be discouraging, but I see so many young people get sucked in to careers like this without fully appreciating the very different reality vs the ideal. Caring careers (nursing, teaching, social worker etc) suck people in with a promise of "making a difference" when the reality is they are often underpaid, poorly treated (by management and the public) and placed in stressful, unhappy environments far removed from the "dream".
