Horses:
First, horses require a lot of space. They need a large pasture or field to run and play in, and they also need a stable or barn to sleep in at night. If you don't have enough space for a horse on your property, you can board them at a local stable or farm.
Second, horses are expensive. Depending on how much land you want for your horse, as well as if you want it to be an indoor or outdoor pet (or both), the price range could vary anywhere from $200 - $500. Third, if it's going to be an indoor pet, it will need a nice bedding area with hay; and if it's going to be an outdoor pet, it will need shelter from extreme weather conditions such as snow and rainstorms. In order to keep your horse healthy and happy in its living situation, make sure that there is plenty of food and water available daily!
