What do you need to own a horse?

Answer. Well it depends...How old is the horse, how long have you had it? You don't need to know much but you do need to know what you are doing. I have been riding since I was 4 years old and I am now 16 years old. I starting training (Working with my own horses) when I was 9 years old. so now I have my own training business. I hope that helps.
