thoroughbred for my Bday.? I live on a large horse farm in a big area of land with a massive house with an arena and fields. We have loads of horses and me and mum and my sister love riding and do show jumping x country and drag hunting. My mum on my twelve birthday got me a big 17hh horse thorouyghbred and she is a fantastic jumping horse and she can jump 5ft and gallop long distance with me. But I am really nervouse that because she is such a delecate breed she might injure herself really easily in the drag hunting. On the coarse there is a really worrying 4ft6 obsticle and what if she trips or hurts herself on the trails. What should I be thinking?
