I personally think you will face an uphill battle with vet school admissions committees as things are now, though it's probably not impossible with the right essays and interview stuff. You can go into school thinking 100% that you want to be in pathology, but things change. Just ask
@twelvetigers, she used to want to do path, spent years working in a clin path lab, and then changed her mind along the way.
So, I definitely wanted to be a clinical pathologist. I put it in my personal statement, I shadowed the rounds at the teaching hospital for about 200 hours (in addition to like 2000+ hours of other vet and animal experience). I got into vet school after several applications.
I didn't make good grades. If you want a residency, you have to do well, and I didn't really - I struggled. I didn't expect to struggle. I wasn't a bad student in undergrad. But I really did struggle. I didn't like vet school, that made it harder. So I wasn't able to get the experience I needed and my GPA wasn't where it needed to be.
HOWEVER, even if I had done well, the idea of another 3+ years in that environment was VERY unappealing by the time I was done. And typically you either need some time in general practice or a rotating small animal internship to get into the residency first, and that (the internship, anyway) would have been miserable for me. GP has been okay, so I wouldn't have minded, but still - that's four years on top of the the four you put into vet school. It's a long haul.
It's gonna be really hard for you to have any idea if your plans would change - I didn't think mine would... I was so certain. But life happens. So, since you just can't know, you really do need to make sure you have some sort of 'plan B' within vet med. Something else you wouldn't mind doing. I ended up in GP... and it's alright, but it's not what I wanted. I'm finding my way to something else now. But the loans don't stop even if you have some 'buyer's remorse' about the whole deal... yanno.
You'll need to get some normal clinic (general practice) experience because:
- They'll want to see it on your application.
- It's a lot of what vet school aims to teach you and it helps to have some understanding of it, even minimal.
- You may have to do it for a year or so in your pursuit of pathology.
- You may have to do it full time if things just don't work out, which is hard to imagine, but definitely possible.
I think you still have some time to mull it over and decide if this is your one true path. If it is, so be it - but you'll have to make sure your application is competitive first, and clinical experience is where it lacks the most.
Also, in regards to vet vs. human - LOOK AT THE SALARIES and make sure you are okay with where you would stand. You may get to see more variety in vet met, but tissues are tissues and you'll see a lot of the same stuff every day with whichever you choose. And human pathology goes a lot more in depth on some things, so perhaps that makes up for the lack of special variety.
