Does she do this on both sides?
I have had horses do this, but what I would do is hold loosely onto the foot, and ASK them to lower it to the desired position. I would describe how I would do that, but I am afraid it would put you in an unsafe position....so try stepping slowly towards her, so that she lowers it.
I am a ďdropperĒ, in that, If a horse pulls away or panics, I drop the foot and start over. Some feel this trains the horse negatively, but since Iíve been training horses for 50 years, that has not been my experience. Me getting crushed by the horse is not teaching them Anything!
I live in KY, and I have no magic here!!I just quietly do my own thing, like Iíve been doing since I got a bratty pony as first horse at age 9. I didnít get a saddle, so all of the ponyís shenanigans were dealt with bareback. Luckily, I had read EVERY book available to me, And they had not just been READ, but studied!! I knew all the parts. I had imagined for so long that I even knew what riding felt like. I had one lesson before I got the pony, and the lady moved, so it was about a year before we went to another stable for a lesson, and at that lesson, I was allowed to jump.
So just keep reading. Donít fret about not using a chiropractor, nutritionist, animal communicator, massage therapist or aroma therapist. The most difficult thing to understand is that the horse KNOWS who you are and what you are thinking! (Thatís the point of putting those sticky notes on the horse in that video....so YOU can focus on a point)
Human must KNOW what it wants when it asks the horse to do it. If human is fearful, horse thinks human doesnít really know. That is why sometimes they wonít go. They are not SURE that human wants to go.
I am sure you will figure all of these equine intricacies out.....I recommend the library.
I don't break horses, I FIX them!
