Thank you on behalf of the horse <3
I’m struggling with a bit of a migraine so cannot go back and read the whole thing to check so pardon the repetition if this has already been addressed.
Will the mare do it on the longe/in hand? If so, and she’s not wearing a ‘could stop a freight train’ cavesson, do it. I’ve been helping someone recently who has a horse with a similar issue and it made a huge difference when I finally got smart and said, “I’m bringing you a dose of sucralfate every lesson and my cavesson is going to live in your barn for a while if it works.”
Huge change. We went from a horse that checked out and said no by rearing, spinning, and bolting several times per session to one that tried twice with the cavesson, failed, and then said, “Oh. Ok. I see there are new rules in place. What would you like from me?” Not many sessions after that he actually started meeting our eyes with very soft, dare I say thankful, eyes. It was like no longer being able to get away with freaking out and tantrumming dramatically set everything straight for him. “Ok. So there are boundaries and I have to stay within them and you are completely fair about them and will never ask me to do something I cannot do. Ok. Let’s get on with it. Pardon me while I relax.”
I’ve always said that a horse that understands boundaries is a happier horse and one that doesn’t is frustrated and unhappy. Usually, it’s pretty easy to set boundaries, but when one has been effed up (like your client’s mare and the horse I am working with) it can take a bit to find the right tool and person to set those boundaries so that the horse understands they are solid boundaries and that they will never be asked to do anything they cannot do physically or mentally.
