Hobble training a horse isn't terribly difficult, I like the Craig Cameron cotton rope hobbles. I start them in the round pen, by attaching the hobble to one side only for a while, to get them used to the feel. Then I switch sides. After they are comfortable with both sides, I attach both. Then I just sit there, give them love and support and let them figure it out. It usually happens pretty quick. I have never had an accident or an injury. Just be there and rub on them and calm them. But beware hobbling a horse doesn't mean they can't run away from you, once they figure it out they can cover some territory....hobbled or not.
