I have a horse on loan, had him since September. During this time he had about three months off due to being lame. When he came back off box rest, he was understandably stir crazy, threw me off more times than I care to remember by fly bucking and bolting. He has been much better recently, but today when I rode, he was like a coiled spring. Spooked at corners, half hearted attempts at bolting etc. I ended up changing schools, walking him around a bit, then doing some very sedate trotting before getting off. I actually got off when walking back to the yard as I felt that he was going to just go, and I didn't fancy coming face to face with the Tarmac from the height of a 16.3. I have been riding for years, but this has completely unsettled me, and it's not just me that he has done this with. Feeling like an absolute failure right now, and not sure what to do, as now when I ride, I am tense and this unsettles him. Any advice, apart from lunging etc etc etc. I need my riding mojo back! Thanks.
