I agree with everyone else. She's too tall for this pony, but she's not too heavy for him. I have a friend who was 5'9 or 10 and about 110 pounds when we started high school, and she rode and jumped her 13.2hh pony with no ill effects. She did upgrade to a 17hh when we were about 16, and this horse suits her much better! She's been leasing the pony to a lesson barn since then and the pony has been kicking butt in the show ring with lesson kids. Unless your daughter goes through a serious growth spurt or has problems with the visual appeal of the pair, then she'll be fine with this pony until she can move up. My friend also had a very strong bond with her pony that she didn't want to give up, but it all worked out in the end. It seemed like the end of the world for her when she had to move on, but it was the best move for everyone involved!
