Horses are possibly the most expensive animal that people can own legally... If you have enough land that is zoned correctly you can keep them at home, but that means if you have just one, it will be lonely. They are a herd animal. They do not think or act like dogs, do not necessarily want to please you or be ridden. You will have to earn their respect by proving you are dominant. This mostly means NEVER let them think they are getting their way about anything. And most will subtly test you, trying you in just about every instance of contact. The best ones are the ones that have grown up with experienced people and never been allowed to go wrong, and constantly used. Expect to pay more for that, but also, keep in mind that you will have to maintain that training or it will be "gone with the wind". Expenses are endless. Even if you don't shoe your horse, the farrier will charge $50 every 8 wks to trim the feet. For an average sized horse, a bale of hay will last 3 or 4 days, at 10 to 15 dollars a bale, it adds up in a hurry. Expensive equipment! Eventually, you will want a horse trailer and a truck to pull it. Saddles, pads, bridles, bits, hoof picks, hay hooks, mounting block, endless expenses. Stable maintenance! Horses eat wood and destroy fences. You will need a good job to go with that horse, so stay in school... Of course that good job will take time and energy too, and you may not have enough left to ride the horse at the end of the day (after you feed, clean the stall etc.). The horse not ridden at least 3 times a week (and more often is better) will "go sour" and not want to leave the stable. A horse that is well taken care of and that comes from healthy stock will need less veterinary care, but still, the day may come. Some always seem to get into trouble, tangling themselves in fences, eating wood, or other things they shouldn't. You can't feed cheap or moldy hay as they will colic and sometimes twist a gut. In short, horses are time consuming, expensive, and the work load is tremendous. I was a horse crazy kid too, so I know what that is like. My best recommendation is find another similarly minded person to co-own a horse with, and share the expenses, riding time, and chores. This person should be compatable and knowledgeable. No one these days with a full time job really has enough time to give to properly maintaining a horse in good riding condition unless they cut everything else out of their life, or are wealthy enough to pay to have help to care for them (or possibly have a big family that is supportive and will help).
