@Ninetails42, can you give us a little more information about your mare? How long have you had her? What kind of lesson program was she in? How experienced were her riders? How old is she (Iâm thinking maybe mid-teens with the PPID diagnosis)?
Do you know if she ever bucked with any of the lesson riders? Iâm wondering if she learned with previous riders that bucking will get her out of work or if this is something entirely new. If itâs new, I would get a very thorough exam to be 100% sure this isnât related to pain.
If the bucking isnât caused by pain then she most likely doesnât see you as her leader, at least not when she wants to eat. I agree with those who advise you to get a trainer who can cowboy through her fits to break this bad habit, but like GraceLikeRain said, not in an overly punitive way. Ultimately, though, youâre going to have to earn the leader position, so look for someone who can teach you how to establish leadership. Can your current trainer work with you on this?
I have one groundwork suggestion that you might try. Put her in a round pen with some tasty hay or something else that she really likes. Take a lunge whip (or stick and string, as Western riders call it) with you into the pen. When sheâs eating the hay, make her move off it and you take her spot. Be assertive but not overly aggressive. Walk deliberately towards her while waving the stick back and forth and make it clear that you expect her to move. Use as much pressure as it takes to make her move. If she doesnât move, smack the whip on the ground. And if she gives you an attitude smack her with the whip, but be sure to stay out of kick range. Youâre not going to injure her, and she wonât hold a grudge. If you watch how horses interact in the field, the alpha horse will first pin her ears when she wants another horse to move. If that doesnât work, the next item on the menu is a bite on the butt. And if that doesnât work the bite will be followed by a kick. You need to be the alpha horse. The goal is for your mare to move away from her hay pile and let you have it, and to do it with respect. This means she moves away with no argument and then turns to face you. When youâve eaten as much hay as you want you can walk away and let her have some.
