He wasn't handled since, that was 7years ago. He wasn't handled because hewill lash out, rear goes to the back corner.He stayed in that stall 23 hours out of a day....they would put up panels to get him in another stall.He's far from the horse he use to be. My cousin learned to ride on him. He's 15 years old, almost 16. Is there any hope? What are somethings we could do? Right now he's in a covered round pen, he has his old halter on that hasn't been off in 7years.
