My TB's were just like Supermane's. With both Cobb and Mikey whenever they started acting up, or in Cobb's case, wouldn't come back to me after a jump I'd drop the reins, talk in a soothing voice and he'd come right down. Constantly giving them something to do helps too. When they get bored I think they're more prone to act up.
My OTTB Mikey was incredibly spooky. He often spooked at unmoving inatimate objects that he saw daily. It helped that I had a really strong bond with him, but to make him get over his fear of things he'd be allowed to check it out, touch it, sniff it, and than he was made to completley ignore it and concentrate on me instead. If he spooked at it again I just kept him going and took no notice of it. Because I didin;'t pay it any attention he learned that it was nothing to be afraid of.
If only for the day, ha ha.
I give myself very good advice, But I very seldom follow it
