Back story: Saddleseat type horse. Quite Nervy. Upright neck who likes to thrown her under neck out. Had very bad dental work when I got her. (Had obviously been floated, but very badly). I struggled for a few years to get her to really accept contact and worked with a few upper level coaches who similarly hit a wall with helping her use her back. Accepted that I must be the problem: too clutchy with the reins when mare would spook/bolt/get tense and so took the bit away for close to a year and rode in a rope halter, and a few times in a bosal (showed Western Dressage once). Horse improved. I improved. We have been having fun putzing around at third level movements while I focus more on my other horse.
Today: Decided to put her back in a bit. Chose the last bit I rode her in: a metal mullen mouth. Mare was quite good. Very long in the neck and light in the contact.
Issue: When I asked for something slightly difficult (basic half pass right & smallish circle right), she sucked her tongue back and got it over the bit (twice). Part of why I had put her in the mullen mouth originally is because she would suck the link of a jointed snaffle back with her tongue. Overall, she was better in the bit than in the halter (lighter and longer in her topline). I don’t feel she was sucking her tongue back from bit pressure, but rather that it is a nervous habit. I could be wrong though, and it is possible that I had more contact than I thought.
I had previously tried KK ultra, KK Hanging snaffle, single jointed snaffle and a locking snaffle. I think I tried a plastic bit, but that was an obvious mistake (grabbing with her teeth). She has also gone well in a Jr. Cowhorse curb and seems to like holding that bit the best.
I think next ride I might ride her with the halter, but have her carry the bit and see if she still gets her tongue over…that would at least take bit contact out of the equation.
I feel like I am so close to having a happy little partner, but still missing something. Looking for ideas.
