I'm going to share my horse. He's 23ish yrs old but doesn't know it! He can still go fast, loves hacks and jumping can be stiff in dressage but has nice paces. I would like the sharer to poopick when they come down (he does 1barrow a day) no stable duties and help with schooling, hacking don't mind him doing shoes but he's not keen on travelling but local show grounds nearby. I would still like to ride him 3x week so should I share him 4x or 3x week? How much should I charge for this? Thanks! I know this is a long msg xx
