So you want to be a veterinarian...
The first thing I am going to tell you is that you better be totally committed to this process, as getting into veterinary school requires a lot of work and you need to be at the top of the huge pile of applicants. In point of fact, it is currently harder to get into a veterinary school than to get into a medical school because there are fewer of them. That means that work can't be your first priority, neither can friends, significant others, or anything else other than the stuff required to get you on the top of the pile. If you are not ready to make that adjustment in your life, you need to reevaluate your career choice. Just loving animals and wanting to go to vet school will not get your there.
The second thing I will tell you; if you are doing this so you can make a lot of money, you are probably going to be sorely disappointed. It's a lot of work and you are going to be very broke before you finish this process. Practicing vets aren't poor, but they experience some extremely long hours and have some very dramatic expenses; many have to run their own businesses and that can be taxing. The more a vet gets paid (and some fields are handsomly rewarded), the tougher the job and the harder the schooling. The other rub is you are going to have to fork out a lot of money to get to where you are going and that means you will probably have a lot of debt when you spit out the end of school. Just applying to vet school can be expensive.
Now that I've got your attention lets begin with some introductory material and then we will work into the more local and direct advice...
