Horses are VERY expensive (obviously). There is board that will vary depending on your barn (I pay $500/month), there is farrier every 4-6 weeks (I pay around $120 each time), and then of course lessons.
Dont get me wrong, owning a horse is the most rewarding and best thing in the world (in my opinion) but just make sure you don’t rush into buying a horse if you don’t have the money. I’m not sure how old you are but if you’re young, having your parents as financial support is very helpful.
A way for you to earn money is of course getting a job. If you can get a job at your barn that would be so helpful because you still get to be around horses and you can get money off board. I do that and I get over $300 off. If I didn’t do that, I don’t know how I’d be able to afford my horse.
i hope this helped and everything works out for you
