I can't tell you what you should do but, speaking as a soon-to-be college senior [I would be graduated already if I hadn't spent 3 years stuck in community college], I know that I changed "career paths" at least 4 times from the time I was a senior in high school to now.
As a high school senior, I wanted to be be a big-time horse trainer and go to Montana State for their horse training program. I thought that alllll the way until the August before my freshman year was about to start [I even got my MSU dorm assignment!]. Then some financial difficulties hit my family so I ended up staying home and enrolling in community college.
Then I spent the next three years in community college, got a general associates degree, and last year finally moved up to my local university.
I'm currently getting a degree in History because that interests me and because it's a pretty general "can go any direction" degree. I'm still pursuing my horse dreams, though in a different way than I thought I would be when I was in high school, and I would still love to make my $$ with animals. However, I'm also getting a degree that's "sensible" and attainable for me, mostly so my resume can look more "well rounded" [like I have other interests outside horses, horses, and more horses] to potential employers.
I think being a vet is a really commendable goal but getting a veterinary degree is TOUGH. There's a reason vets are in high demand!
Definitely shoot for your dreams if you can, but make sure your dreams are attainable. And be willing to let yourself switch dreams. At your age I probably would have gotten SO mad if someone told me that I would be getting a History degree in 5 years...but I am! Haha
That's the one thing I can recommend about a community college experience - in getting a general degree, I had to take SO MANY random classes that I really got to feel out my interests beyond a "hey, I think I miiiight like that subject, but I don't know."
And really, being a vet is wonderful wonderful goal. I don't want to dissuade you from that at all! But make sure you don't paint yourself into a corner, as it were, while getting your vet degree. :)
