When she comes in heat, she becomes IMPOSSIBLE to work with. Anytime you ask her to move under saddle she stops and squirts. I've never seen anything like it. She gets pushy, unresponsive, and downright frustrating to handle. She's somewhat pushy on the ground anyway, which we're working on (but not as often as we should since I've been distracted with my 2 new horses lately), but when she's in heat, she won't let me touch her neck up close to her ears and she will get downright balky.
She is with 2 other mares, and she is not the dominant of the 3. She is in the middle. Whenever the dominant mare leaves, this mare will start squirting and going bonkers. Anytime you use leg pressure or ask her to move out, she squirts. I really think she is uncomfortable and I feel bad riding her when she's in heat, so we did some groundwork mostly today after a somewhat short ride. She's also had 2 foals, but it was a long time ago, if that matters. She also gets Mare Magic.
My question... is there some sort of way to stop this? She will not be bred again, and I think she is genuinely miserable when she's in heat. Her owners and I really want her to be comfortable and enjoy her job, not miserable like a chick on her period with bad cramps. Ladies, you know what I mean. They even talked about a hysterectomy but I'd imagine that's expensive since it's so invasive. Is there a shot, or...?
