What do you do about a horse that ignores your presence completely, and when you step in to work with them, they just avoid any and all contact? Like - a horse you can walk up to in a field, he won't run away from you, and when you are trying to put on the halter, he pulls against you and tries to keep his head down so he can eat? Like he's thinking, "Puny human. Do what you want to me, but don't interrupt me being social and eating and whatnot."
I think I have a pretty good grasp on what to do, but I'd like to know if anyone else has dealt with a horse like this, and what you've done.
