Do you have to go to school to give horse back ridding lessons?

No, but if you are planning to have a place with horses and make a living out of it then yes. You would need to take equine health classes, training classes, etc. If you just want to ride horses you dont even need to own a horse, just find somewhere you can ride one. If you have any more questions, you can talk to me an howrse.com, I am Katalina98 Or my email is katalina989898@ymail.com
