I ride a 17.1hh Irish Sport Horse for a friend. He is 19 years old and used to hunt and compete in showjumping competitions when he was younger. I'm not 100% sure of his history as he is not mine, I only ride him but as far as I know the only reason he stopped hunting and showjumping was because he was sold to his (now) owner. I started riding him in October 2010 and we were jumping 2'6" pretty regularly. In November/December time he got very severe laminitis meaning he was on box rest until March when we slowly began bringing him back into work. He has had a few problems since with thrush, recurring laminitis and dust allergies but he is now doing well and I am doing a lot of canter work with him. I want to start jumping with him again but I need some opinions. When he used to showjump, he was jumping 1 metre+ courses so my problem is that he finds small jumps very, VERY easy. I just want to know how slowly I should take it. Obviously I know I should build up slowly but it's just too easy for him. What do you think?
