I'm a bit lost on this one, so maybe HGS will have some ideas for me. I have a mare who I bred, and she can be a problem in her stall. She is normally a very sweet, laidback mare, so it's an odd behavior for her character. Her mother was a little defensive in her stall, but it never progressed beyond minor ear pinning (mare face, lol). I knew her behavior came from some training she had probably a decade before she came into my life, and, again, she was super sweet and the ears would go forward as soon as you gave her a pet. Her daughter, though...She'll be 9 this year, and it has progressed on and off over the last few months. As far as what she does, she's really just defensive. It is at its worst when you're cleaning her stall. You have to keep an eye on her, as she will spin around for no reason at all, pointing her hindquarters at you or almost running into you. She had never offered to kick until this past week, and when she did, it really shocked me. It was more of a warning, but for no reason (my mom was on the opposite side of the stall from her, cleaning it quietly, and we have good sized 12' x 12' stalls). If it were just the ear pinning, I wouldn't care. I'm just not sure what to do about the spinning and her pointing her butt. When we get after her, she gets even worse. She is perfectly calm & quiet at all other times in her stall. It is only at cleaning that she is an issue. I'm not sure how far or how hard to push, I guess? Or exactly what the best way to do it would be. I don't want the stall to be a scary place for her, but this behavior is unacceptable. I have no issue being very firm with a horse, FWIW. If I need to do that, I'll do it. I just don't want to make a situation even worse. She is turned out everyday. She has free access to hay when in her stall. There is no grain or soy in her diet (we feed hay pellets, a complete vitamin/mineral supplement, and alfalfa hay, all in conjunction with working with a vet). She was in work up until this cold snap, and she will be going back to work Sunday/Monday when we have reasonable temps again. I have not noticed a difference in the behavior with her when she's working vs. when she has extended time off. She has never had to share food with another horse, either. The stalls have solid walls, so she cannot even see the horse next to her. I have treated her for ulcers, but there was no change. I am debating doing another round, which is why this post has been made. If people think this sounds like an ulcer-y type thing, I'll do another round of UlcerGard and EquiShure. I've just never dealt with a horse like this, and it gets a bit old throwing money at meds/treatments unless other people agree with me that it'll be worth a try.
