It suddenly occurred to me that you might be having issues with your parents as much as the horse. It's likely that you chose this horse, and promised he'd be the right one for you. It turned out he wasn't and you have to convince your parents to help you do something about it! I know in this situation my parents would have been angry and might have made me give up on horses altogether. Have you had any luck with them, yet?
Yep, your parents are angry with you and trying to prove a point but unfortunately, they are also risking your neck by letting you keep this horse.
I can't blame them for not wanting to pay for training. The cost of ownership plus
training is a real financial burden. And, of course if you had bought a steady,quiet, fun horse you could handle, you wouldn't really need to add training.
Just look at it this way-to own a horse is roughly equivelant to going to the dealership and buying a really nice brand new car or truck. And, of course you never actually pay it off like you would a vehicle. Horses are purely a luxury item and we horse owners sacrifice
a lot to own them in both time and money.
Since your parents are making the decisions, I assume you are under 18 and that means your parents truly own the horse. Until you reach 18 (in the US) you cannot own property or enter into a contract. They can actually sell the horse anytime they want. Be careful not to anger them, just approach the problem as maturely as you can
You may have to just sell the horse and go back to lessons (for a while) so that you can try to prove to them that you are responsible enough to own again. If you do get a chance to own a horse again, please take a trusted trainer with you for every single horse you look at. (Pay them for their time). Do not fall in love with the 1st one and do not
buy for color.
Get a horse that meshes well with you and is trained to do everything you need so that no one has to take on the extra training expense.
Take everything a seller tells you with 'a grain of salt'.
