The prospects for veterinarians is going to vary a little depending on which country you plan to work. At the moment I can only really speak from the perspective of having worked as a veterinarian in Australia for over 5.5 years, but I do suspect that the prospects and challenges are somewhat similar.
I'm not entirely sure what kind of info you'd be looking for, however there are some rather solemn facts and figures about the veterinary profession at this website which an ex-colleague of mine started up:http://ausvetnet.wor...thor/ausvetnet/
It may not be the kind of information you were hoping to read, but IMHO (and in the opinions of many other veterinarians working at the coal-face), the veterinary profession is facing a significant challenge going forward from here. We have issues with oversupply (of both veterinarians and veterinary clinics), said veterinarians that usually have significant student debt which they have issues paying off due to their surprisingly low remuneration.
Bottom line I guess is, a great investment in time and money is required to be a veterinarian, but it is debatable as to whether the profession repays in kind. The rewards from this job are intangible at best. If you love animals, consider that a love for people is of greater importance in this job. Also consider working in a job that is more financially rewarding, and volunteer your time (and/ or money) to the service of animals. A person considering to work as a veterinarian should also be open to options to medicine and dentistry.
It is regretful that I've come across your thread almost a full month after it was posted and I'm not even sure if you will receive this response, but I am bound by my conscience to inform prospective veterinary students of the potential pitfalls...essentially, to encourage them to consider other options and be careful about looking at things through rose-colored glasses.
Anyway, feel free to write me if you have any other questions.
