My friend is looking for a horse and she found one that she really likes but his jumping form isn't so good. He is very green, an OTTB with not a lot of over fences training. He is extremely brave and a pleasure to ride. The horse is owned by a friend of a friend and our friend test rode him to see if his form improved if the jumps got bigger. They were up to 4'3" and he was not touching anything but still jumping behind at the knee (knees lagging behind, not tucked up). She really likes him a lot but we are not sure if this is something that we can work on in training (we have a trainer) or will never change. She'd like to do Equitation and or hunters, but honestly, she hasn't really ridden in about 6 months since the horse she was leasing went lame so she'd do jumpers too if needed. She just wants to ride something fun and trustworthy.
Just wondering if anyone had any experience with this. She has a video that I can post of him jumping higher but here is one example at a lower height.
