I'm waiting on one more school to see if I'm accepted but on the mean time i'm preparing to apply for next cycle. Regarding the personal statement, do i have to rewrite it completely or do i just add the experience i get in the mean time??

I think people underestimate the importance of the personal statement. If you don't get in, I would urge you to take a hard look at it from an adcom's perspective. Remember that they have to read hundreds of statements every cycle. I know if I had to do that, my eyes would eventually just glaze over unless something really grabbed me...
I come from a writing background and feel strongly that you really need to figure out what makes you special and tell your story in a way that sets yourself apart from the hundreds of other great applicants.
Not that it's necessarily true for your case, but I have read the statements of several people who were rejected and/or waitlisted despite good stats. I completely understood why after reading their statements. They came across as boring or wishy-washy about vet medicine even though I knew the applicants were nothing like that personally. 🙁
Many college career-services centers or writing centers will edit your personal statements for free. Take advantage of that or have a friend (or several) with great writing skills pour over it with a fine-toothed comb. It could make the difference between acceptance and another rejection.
Following this advice I was amazed at how much my statement evolved through the rewrites. It was always me, but each rewrite helped to present me in a more precise and interesting manner!
ETA: And so true about the "I love animals" thing. Someone told me never to put those words in my statement unless I wanted to be rejected immediately. 🙂 She was kidding, but not entirely. 😀
