Buckly took to the bit with no trouble at all. He never even chewed it. First horse I've ever started that took it so easily. Maybe Pistol will also. I do the bit before any other harness parts. Maybe that's not the right way. I let them wear it around for a while, and take them for walks with it under the halter.I didn't realize that Buckly and Pistol were so similar. Pistol is 8 and was also a stallion. He hadn't been handled but he's gotten over that. Have you already introduced Buckl to the bit? I'm pretty sure I'm going to need to pick your brain as to what you are doing with him because I've never started one driving before. We've gotten as far as introducing all parts of the harness and one session with "shafts". After that I'm at a bit of a loss....
