There is a vet school near me. Tuition for 4 years is $100,000. It will take years to earn that back by working.
I took some of the pre-vet classes during college. It is hard. If you are studying animal reproduction, you don't just learn one animal (like dogs and cats), you learn everything- dogs, cats, goats, sheep, horses, cows etc. I think being a doctor would be easier. At least doctors only need to learn human anatomy and physiology.
I wouldn't do it, just because I was burned out by the end of college. To me it is not worth the stress. And the other issue is, if you work with animals all day, you are going to be too tired when you get home to enjoy your own horses. Most of the vets I know stopped riding. They have horses. They just don't get to enjoy them.
Plus, being on call at all hours. My vet came at 6pm and stayed til 10pm on Saturday night with a colicy horse. Another vet had to come early on Sunday morning to help with a colicy horse and we had her on hold the night before as we weren't sure the horse would make it til the next morning.
And the vet that stayed til 10pm, had another emergency call after he was with me!
The other issue I see, is that if you for some reason get sick, and cannot work as a vet, what will you do? Especially with all those loans? Younger people don't plan on getting ill, but sometimes the unexpected happens.
You can do it, but I would consider it carefully. Vet tech work might be an easier field to get into. There is a demand for vet tech managers who have at least 5 years of experience or more and are certified.
