I work at my barn in exchange for lessons it doesn't make me any money but it sure saves me a lot.
hello! I am a young rider myself and I've made lots of money, and continue to do so by caring for horses when their owner's are out of town. I took care of one horse for a month and made two hundred alone. make sure all boarders know that you are there to help. by doing this you seem like a good go to.
Yes there is! Being at groom at shows, stable hand at the barn or riding ponies for others is a great way to make money at a young age. I currently work at my barn to work off a lesson. Hope I helped :)
