He is a 16yr OTT who was a school horse before I got him. But he has a few things that he did not get trained well at and this is one of them. Now don't think I just let him walk around with his lead on hanging on the ground, because I don't, but it has happened twice now in 2 years and I would like to teach him to be calm if he steps on his lead. When it happens he yanks his head up really hard and once broke the breakaway part of the halter. I think him learning to be calm would be a great lesson for him to know incase of any other emergency.
Any advice would be great.
