As someone who was dismissed themselves a few years ago, I’ve looked into this a little bit, but ultimately decided to no longer pursue vet med.
From what I’ve read/seen/been told, it is
possible, but not very likely. A lot will depend on where you choose to apply; there are a good number of vet schools who outright refuse to consider students previously dismissed from another vet school (off of the top of my head, I know Mississippi State is one of them and they even state as much on their admissions website). Overall, it does seem to be the case that the Caribbean schools are more forgiving and are more willing to offer second chances than US schools. Of course, then you have to weigh the costs of that education on top of however much money you spent during your time at your previous vet school (and potentially undergrad, too, if you needed loans for that). A lot certainly rides on personal circumstances, but it may or may not be financially doable or even advisable and that’s something that you’ll need to evaluate yourself; for me, I cut my losses and moved on. I’m considering grad school in another field (provided that I snag a state government job offering tuition assistance that I’m currently interviewing for, ha).
Also important, like
@MixedAnimals77 stated above, is to consider what it was that caused you to founder academically to that degree in the first place. Were you dealing with physical and/or mental health issues? Family or other personal problems? Did you bite off more than you can chew with extracurriculars and/or work on top of school? Or were you simply overwhelmed by the material and weren’t able to pull the grades you needed (it happens)? Whatever the case may be, have you thought through what caused the failure and are you prepared to ensure that it does not happen again? You’ll need to demonstrate to any schools you apply to that you have/are actively taking the steps to addressing what caused you to slip last time.
In your position, I would directly reach out to the vet schools you’re interested in and ask if they would possibly consider someone previously dismissed from another vet school for admission. I suspect you may get a good number of nos, but if you do find a school that would be willing to consider your application and work with you, do your damnedest to show them that you’re over that past failure. Ask them if there are any steps that you can take toward that aim, whether that be taking additional upper-division science courses, seeking help for any health issues, or whatever the case may be.
Basically, yes: people have done this before, but there are additional hurdles you’ll likely have to clear and you’ll need to be sure that you’re applying to schools that won’t simply discard your application once they notice the prior dismissal. This may require additional sunk costs in both time and money. It’s up to you whether or not that is worth it.
