So I have a 5 year old retrained OTTB. He was retrained for jumping, and now im riding in a Western saddle. All seems well, he's taking it very well. Now down to my question. Do you think it would be too much if I started training him for something else, say driving? I don't compete, and the driving wouldn't be competitive either, just something that he would be able to do, and could do once every while. I don't wanna overload him. He's a very calm horse and puts up with me riding with tarps tied to the saddle, walking over tarps, etc. I just wanted to see if you guys thought it would overload him at all. Thanks in advance!
