Even though we've had some set backs, Cory has made monumental strides this past year. He went from being unable to be caught, no trust of humans, buddy sour, and stuck in the fight or flight reactive mode; to a growingly confident steed who rides out alone.
Cory still has some PTSD moments here and there, but they are becoming less severe. I am able to walk up to him out in a 10 acre pasture and catch him 80% of the time. He is now starting to come to me in the pasture. This has been our biggest challenge. For him to choose me over the herd takes a lot of trust on his part.
In the last month I have began weening him from the herd. His extreme buddy sourness is like that of a nursing foul. So I decided to treat him as such. He is now in an adjacent pasture to the herd where he can visit over the fence. The next step is to move the herd to a further pasture where he can only see them. Because of his age, never being alone, and his anxiety, I have decided to take this slow. I am slowly becoming his greatest source of comfort. He equates me with relaxation. Now when I visit him in the pasture, he yawns and rolls his eyes just at the mere sight of me.
Cory and I are riding on a regular basis, slowly introducing more and more new environments. We have ridden out on the trail with his buddy Pearl. We rode down a busy road way to get to the nearby foothills. He did quite well with Pearl at his side. On the farm I ride him out alone in increasingly "scary" stimuli. My goal is to be able to ride him anywhere alone with confidence that he will maintain his composure when presented with a scary situation.
Over all, I am proud of Cory's progress given his age and circumstances he came out of.
