The gelding has adapted well and has a wonderful sweet disposition. As far as retraining, I am finding some strange "quirks" that I think may be a holdover from driving. I know nothing about driving and am hoping someone who does might post up here.
When I lunge him to the right, he is his usual calm self. I just walk up, turn him to the right and cluck-he stays on the circle with no problem. However, when I try and go to the left, I.e. I approach him and try to get along his left side he looses his mind and backs up and blows. I mean he flips his head up, quakes and motors backwards all the while keeping his head in line with my body. The first few times...wow he was just a mess. Acted like I was going to kill him if he didn't back up.
Before anyone asks, his vision is fine according to the vet . In the past few weeks I have gotten him to calm down and am now able to rub the lunge line and the whip on his left side, then I can motion him out though he still blows and takes off doing his huge earth shattering trot for a few minutes until he settles down.
Could it be that the former owner-whom I can't contact-had some sort of "back up" command? I mean this guy who'd rather sleep than work just about levitates himself back in a straight line.
Oh, and this only happens when he is hooked to a lunge line, never on a normal lead line or when he is bridled which is why I wonder if it is some sort of command rather than a training issue.
