I had the vet out for Si today and it didn't go too well! He needed a jab of local, followed by his vaccination, then once the local had taken effect his microchip inserted. The minute he saw the vet and the needles he tensed right up, and as soon as she put the needle in he was straight up in the air. He didn't just go up once though, it was at least a dozen times and at full height aswell. He trapped me and the vet against the wall in the process and the whole situation was pretty dangerous even though he's only a small pony. He landed on my foot leaving me with a big bruise and he caught the vets arm on his way down at one point aswell but to be honest I'm just so relived he didn't cause either of us any more serious injuries. In the end we had to twitch him and even then he was playing up. I'm a bit worried that he's going to make a habit of this though as although he's never reared full up before today, he has done smaller ones with the farrier, being wormed etc. It seems to be his chosen form of protest not just when he's scared but when he simply doesn't like something. I'm also worried he might rear up when ridden as I'm in the process of breaking him at the moment. Is there any way I can prevent him from getting into this pattern? I really can't think of anything I can do as obviously I can't always predict when he's going to do it. Or could someone suggest a good way to deal with it when he does? As much as I love him I won't keep a dangerous pony if it develops into a bigger issue, but I really don't want to sell my boy! Is there any way to nip this in the bud? Thanks in advance as always.
