Obviously I don't know you, and I don't know your skills, so keep that in mind. Do your parents know that you are responsible enough to own and take care of a horse? Owning a horse is not a thing like owning a dog or cat. They are alot of work, often involving blood on my part with matince... don't ask .
Maybe you can take horse quizes online or in magazines so they know that they can see that you know enough about them.
My parents know I'm responsible enough and they know I have the skills to take care of a horse. I voulunteer at a barn near me, and I always get compliments around my parents about how hard I work, how good I am with horses, and how well I ride. They know that I wouldn't sleep at night unless my horse was happy and comfortable.
I bought my first horse. I got a job and I made payments on him until he was paid for. I paid all my vet bills and board... etc. My dad was impressed by my "grown-up-ed-ness" and he bought me a $600 stock trailer to haul him with. I started hauling my own horse to lessons and shows at 16.....
I am really trying to do this, but I live in a really small town (there's not many jobs.) and I'm only 15. I'm going to get a job next year at the vet's and at a local restraunt, but I'm not sure if that's going to be soon enough to buy my horse. I think they are trying to sell him soon.
Those are good ideas...keep trying. If it doesn't work, then you'll just have to wait until you have the money to get one yourself. Remember, you have your wholeee life to get a horse. Just enjoy the riding for now! & being around horses too...it's a great privilege.
Sigh...I know I have my whole life, but this horse is really special! He's my baby. Our hair is the same color, we're both the same age (supposedly) and we're the same exact height. I keep on telling my parents that it's a sign! LOL! I am enjoying the riding, but I can't ride him right now (which is KILLING me!) , and I won't be able to ride him English.
I'm not giving up though!
