Something needs to change. The veterinary school application process is seriously a mess! There is no way that adults who are at least 22/23 and graduating from good colleges with strong GPAs should have to put their lives on hold to apply to vet schools once a year. I realize that there are some people who are perfectly happy putting in a gap year... or two or three... working in the field as a vet assistant or a tech while pinning their hopes that MAYBE next year they will be accepted, but that's not for everyone. And I don't think we should have to do that either; especially after doing a lot of the animal-related work experience before applying to vet school. People don't realize that not everyone can live off of their family until they're 30 years old. Also, there are so many variables that can interfere with waiting to apply to vet school that it might never happen. There are not enough accredited vet schools in the US, and, as a result, really strong students with GPAs of 3.5-3.8 are being passed over because of the volume of applications. It's infuriating! Society needs more people who are DVMs, so why so difficult for strong students to find a place? This is screwed up!
I strongly encourage you to take a deep breath and take a step back. I understand not getting in is frustrating and disappointing, but this mind set will not get you into vet school either.
1) I can guarantee that the application proscess is not going to change anytime soon. It has been the same way for years and follows suit of the majority of MD program applications as well.
2) If being able to apply only once a year is the concern, the island schools take applications multiple times per year. Not that I recommend island schools because of the price tag but if the amount of times to apply is the issue, there is a solution.
3) It is up to you if you put your life on hold. If you didn't get in figure out what it is that you want/need to do in life in the mean time. Not getting into vet school is not the end of the world unless you let it be. If you don't want more animal hours/can't afford to be a tech/assistant consider what you can do. ie. Have a degree in tech? Go get a job in tech and volunteer in your free time to keep your foot in the door. Go work at a human hospital. Point being no one has to live off their parents and put their life on hold
4) One could argue there are plenty of vet schools in the US. Tehcnically there's a "shortage". However, the field is also starting to see stagnation and regression after the last few years of growth. If too many schools open, demand along with salaries decrease and you end up with a situation similar to pharmacists (lack of jobs and lower pay for what they're worth). The true shortage issue being in food animal/ rual/ mixed is never going to be solved by opening more vet schools. Also just because you open more vet schools does not mean one would get in.
5) Are there people who would probably make wonderful veterinarians not getting into vet school because there are not a huge portion of seats, sure. However, there are more factors than just GPA (yes I do believe you need a strong GPA to suceed) but experience, how one plans to contribute to veterinary medicine, and overall attitudes can majorly impact admission decisions.
6) It is up to the individual to decide weather or not they can/should apply to vet school multiple times. For some people vet school isn't going to happen. For others it may happen on the 1st or 5th time. In the end though, it is JUST a job. If you ask me, your work environment is much more important than the job you actually do. I have a good work environment (which is arguably more important than any job), but relying on your job to make you happy and fulfill you often leads to disappointment. Sure I get some satisification from my actual job, but if I hit it rich tomorrow I would probably quit to do the things I really love. Ultimately one's self stands in their own way of happiness. Am I lucky to have become a veterinarian, yes. Are there days I would rather go work in a cubicle, you bet. However, I am happiest because I choose to be. Have that plan b, I promise it's not the end of the world. I'll say it one more time, being a veterinarian is JUST a job.
