I volunteer at a theraputic riding barn about ten minutes from my house and they treat the horses like gold. The are only used in a max of two lessons a day, so they aren't worked too hard. We looked into it before we found a leaser for Ace. They wouldn't take him though becase he has uvietus :/ If you horse is in good health and pretty bomb proof you should have no trouble fiding a therapy place to take him. Some, at least the one I go to, will lease the horse for two years and then give then back or renew the lease. Maybe that could be an option incase your situation changes? I'm sorry you might have to give up your horse, hopefully you can find them both a good home!
