Free leasing a horse?

Okay, so i am maybe going to free lease a horse, and i want to no what will i probably have to pay for in the deal and how much are vet bills and dental care?? oh and how much is horse feed? thanks for your help :)

how long are you leasing it? horses only need dental care if they are having issues eating. vet check ups are only once a year for vaccines unless the horse gets sick, lame, or injured. you can worm the horse your self. normally the owner of the horse will pay for the vet bills UNLESS you hurt the horse, or cause the injury. normally they also pay the ferrier, unless you want the horse shoed if it isnt already. LUCKY YOU! free lease!!!
