I rode him and you could be approaching something as simple as a rock pile and suddenly he will spin and run and if you prevent him from running he slams you into anything he can. He did this 3 times to me in about the 1st mile.
Each time he did this I hauled him down after the spin, slammed the spurs as hard as I can while yelling at him. Again I would slam him as hard as I could. I ride with totally loose reins,no contact so he is really free to spin.
After the 3rd spin he settle right down and continued the ride for the next hour without a single incident. I know of 2 places that his owner could not get him to go past but both times I touched him with the spurs ,steadied him with the reins and he walked confidently past these obsticles.
I know the next time I take him out he will settle right away. He is more afraid of me then of the things we run into.
This horse is not really afraid, it is a habit that he got into because of a weak rider, one afraid to put the fear into him. By being rough, and I mean as rough as I can he learns to stop playing games and settles into his work and by settling you actually leave him free to do his job, a looser rein and more freedom.
