I have recently adopted a 15 y/o Thoroughbred gelding, he's an ex racehorse and was ridden (poorly) after his track days and has acquired more than a couple bad habits. To give you some background first he was underweight and lame when I got him, and now - 3 months later - he's up to a healthy weight, getting turnout, and hasn't a sore muscle for miles...however, now that his personality is really shining through we've hit some bumps. I started riding him only rescently because I wanted to wait until he gained at least 200 ibs before he held weight, but I had been round penning and lunging him increasingly to get him to build muscle. I made sure to only to a little bit at a time and he's really come a long way, he's proud and smart, and more than a little "quirky". Now my problem...When I first started getting on him he seemed a bit skittish, which I figured was because he was still getting used to being outside and here I go and take him out of his element again, so I didn't think much of it, we worked through it in 10 minutes of walking and trotting...no big deal. I was absolutly convinced I found my perfect horse, and here, a couple weeks later he seems to loose his mind when I get on his back, I sit quietly (easy on him) and he never unseats me, but he won't calm down either. At the end of every ride all I end up accomplishing is getting him to walk or trot quietly. As of the last ride he's added bucking and rearing into the mix...I hate to sound innept, I have exhausted all of my ideas and obviously need to go in a new direction...can any one help or have you been in this position? Any serious advice would be greatly appreciated. Thank you.
