Brutal hint from one who knows:
Don't go the veterinary route.
Not only will you suffer the grueling hell of vet school X 4 years (which is worse than almost anything I can think of at the moment). But once you graduate, find a job as a vet, and start working off your massive debt load, you will work 80 hour + weeks trying to save all the animals while neglecting your own, having no life, making a comparatively crappy income (especially considering your vet school debt) and a quality of life that is questionable, while lecturing clients day in and out about the quality of their pets life, and putting down animals 24/7 for reasons too numerous to name. And did I mention vets have one of the highest suicide rates of all the professions? People think it's all, like Animal Planet. The reality is far different. I won't get into the abuse and neglect you see daily, and the clients who expect you to perform miracles with $30 in their pocket, and cuss you out when you can't fix it, or they don't want to hear the options you give them.
Sorry if this upsets people, but...been there, done that, will be paying off my now-scanty 70K debt till I'm in my 70's or die. How do I stay at home and play with my chickens and dogs and have a decent quality of life? Quit being a vet and went back to nursing. School nursing, to be exact. I make a little less than what I made as a vet, it's fairly happy work, I don't work nights/weekends/holidays/24/7, have to be on call, all that jazz.
Oh , and the kicker? Veterinary people can be some of the most catty, back-stabbing people you ever worked with. I don't know why this is, you would think all animal lovers are sweet. But they can be up there with seasoned, ICU nurses with some new grad meat to work with, lol.
Sorry if that not what you want to hear, but that's one ex-vet's opinion. There are alot more of us around than you would think!
Just some honest advice. Veterinarians are always working. Even when they're not. Brutal, brutal lifestyle for most. Interview some vets before you decide that's what you really want to do....or develop an incredibly thick skin and learn to function at 200% with no sleep or food, ever. Just sayin'.
