Blackie has always been a sweet and tolerant horse — never biting or kicking, even with kids handling him. But since he started being used as a school horse, his behaviour has changed quite suddenly. Within about two weeks, he began reacting to the girth, and now it has escalated to where even bringing a saddle pad near him always triggers biting or kicking. I’ve had him checked — no ulcers,but the physio found quite a few blockages, but those have been worked through, and physically he seems fine now. She did mention that he might associate saddling and riding with past discomfort or negative experiences, and that he could be anticipating pain. Over the past week I’ve stepped back and focused only on groundwork and rebuilding trust. He is honestly amazing in that space — he follows me without a lead, mirrors my movement, halts, backs up, and is completely relaxed being touched all over, even his belly. And lowers his head for the halter. It really feels like our connection is strong again. But the moment I bring in the saddle pad and move toward the saddle area, he becomes tense and reactive again. When I bring the saddle pad near his face he wants to bite it. We then go and do some groundwork and come back. He desensitized up to me bringing the saddle pad near his head, cheeks and ears. As soon as I go near his neck hê bites and goes for the kick. So I really want to ask: Do you think this is stubbornness, or is it genuinely fear/association? And how would you suggest I handle this going forward? Also, the riding school would like to start using him again — what would you recommend I say to them? I’m worried that rushing the process will undo the trust we’re rebuilding. She did use him whilst him biting and kicking and then just nudging him with a stick - I’m not sure that is the right way to go about this? Once the saddle is on - he is perfectly fine to ride and doesn’t buck or anything. My biggest goal is to help him feel safe with the saddle again so that I can ride him, but in a way that is calm, positive, and fair to him.
