For the person asking why Penn is awesome...
1. Location - no, Philly is not my favorite city. But it is a CITY. This means that when class is done for the day, I can go to the art museum. Or the theater. Or the opera. Or go for a run in the park. I go a little crazy when school = my entire life, and so I enjoy being able to chill with normal people leading normal lives that have no relation to vet school. It's just easier in a city.
2. New Bolton Center. Need I say more? The equine hospital is top notch. It's not close to the Philly campus, but that's because people aren't going to bring their large animals into the city. As far as I know there's no official ranking, but CSU, Penn, and Davis seem to have some of the best equine programs. If I wanted to do food animal, Penn wouldn't be my top choice, but I'm between equine & small animal... and I can get a good small animal education anywhere.
3. Ivy League school. Does it really matter in the scheme of vet schools? No. But everything from Wharton to the medical school to the undergrad program has a fantastic reputation. I have friends in wharton and various undergrad and grad programs. I haven't heard anything bad except some arrogance among the students (which I've heard is largely absent in the vet school). Penn is dedicated to providing a high quality education to every one of their students.
4. High caseload. This is one of the things that appealed to me most at my interview. The students kept talking about how the 4th year students at Penn have several of their own cases to juggle, while 4th year students at other schools may all be sharing patients. It helps ease the transition into practice after graduation if you're used to acting independently and taking control of the cases.
5. New program instituted in the first two years to provide additional clinical experience for the students. Penn recognized their weakness in not providing much clinical experience in the early years and has acted to fix that gap. I can't remember the name, but the current students seemed to think it's a good addition. It also helps remind students of the bigger goal when they're slogging through anatomy.
6. PAWS. Penn has a program set up with the local animal shelter where the vet students can go over and practice spays and neuters. The first and second years can do the neuters (after getting certified in knot tying) and the third and fourth years can do spays. It's a great way for the students to get more experience while helping to control overpopulation in philly.
7. Large class size. This might be a drawback for some people, but I like having more people in my class. I will get to know the 120 people very well, but I won't be forced to spend tons of time with the few I might not like.
8. Research opportunities. I loved doing bio research in undergrad and would love the opportunity to do more research in vet school. Penn has some great resources for summer programs, and you can add a PhD to your DVM partway through your education.
9. 2 hours from the beach, NYC, Baltimore, etc. Valley Forge State park nearby. Tons of outdoor stuff once you leave the city. Skiing about 45 minutes away. Basically anything and everything you want within a reasonable distance. (except great mountains. You need to drive a few hours to get to them).
8. Philly soft pretzels. I could go on and on and on about why I like Penn. But really? 4 more years without delicious, amazing, salty, good philly soft pretzels would be torture.
(only drawback? Penn is still my most expensive option even though it's my IS)
