Gidget, this works with all horses of all temperments. Take a stout stick at least 4' long and wear comfortable footwear and be prepared to walk her down. Leave your anger, impatience at the gate. Keep the stick pointed to the ground and behind you. It is there, in case. Circle around, oh 30' away until you are directly behind her, in her blind area. If she's grazing, good, then run directly toward her rump with lots of energy and wave your arms out sideways so you look huge. She will likely take off and that's what you want. Again get in behind her and do the same thing. She will start keeping an eye on you but one eye isn't good enough, you want both eyes. What is going on here is you are moving her off her grazing spot like a dominant horse will. So you are letting her know that you are the dominant one, not her. When she will face you with both eyes stand still, lean forward a little so you appear smaller and extend your slightly closed hand. She may come and touch it, or not. If she doesn't, step back a few paces, wait a few seconds then step forward and reach again. Don't try to touch her, she must come the last inch. If she turns and walks away or suddenly bolts away your must immediately turn and walk in the opposite direction. Begin your circling and chasing again. Take the time to do this now and do it 4 or 5 times day if you can. The goal isn't to catch her just yet but that when you enter the field and walk toward her that she will immediately turn her hiney away and face you, no ifs, ands, or buts. I did this while the horse was not wearing a halter. I knew it was working when he stood quietly for haltering. When you first chase the horse, you are just chasing it off the spot it was eating. Don't run past that. That is now your spot, for a few seconds. She may run a good distance at first but if you always stop at her spot she'll get so it's only a few strides. And believe me, she'll be trying to figure out what's going on. Most horses don't like to be the dominant horse as that's the one that rarely gets to relax. It's job is to keep the herd safe. It's much easier to keep an eye on the dominant horse and you will find that as you assert your dominance she will become willing to keep an eye on you, altho you want both eyes. There's an old cowboy adage, Beware the horse that watches you with one eye.
