My 5yr old has just started grinding her teeth. She goes really well under saddle - soft, responsive, and coming through - and she finds all the dressage work pretty easy and doesn’t usually have any trouble with it (yay for purpose bred horses with good conformation).
I think the cause may be bit related, but I haven’t ruled out pain. She just got her teeth floated about a month ago. I want to get her saddle fit checked and have the massage therapist out. I don’t think ulcers are an issue as she isn’t showing any other symptoms. The reason why I think it is bit related is I did some ground work with her in her bridle, and when I asked for flexion/ bend she would start to grind. She keeps her mouth closed, and otherwise doesn’t seem irritated.
Any ideas? I have a lesson mid week, so I’ll ask my coach about it then, but wanted to see if I could start to solve it now.
