OK, before anyone asks, yes she recently had her teeth done, and yes, I do ride her with a very light hand, and ask with my leg.
Now, I know most, if not all of her issue stem from the fact that she was used as a lesson horse at a very young age. As in two. And now she pretty much just needs to mature, and relearn how to be ridden from leg to hand.
If I had an arena, I would stick her in mild snaffle, and just keep at it, until she matured, and learned that I am not going to yank her face off. However, I do not have an arena, so we ride around my neighborhood - I live in the country - so I have to stay somewhat safe, and I do need to be able to stop and turn at some level.
So far I have tried: Plain D ring, Rubber Nathe knock off, (chewed and tossed her head at these) Mullen mouth Kimberwick, Mullen 2 Ring Happy Mouth Elevator, (Totally behind the bit, even with a total loose rein. She was used for lessons in a Kimberwick, and pretty much hates it) KK Oval Link Egg Butt, French Link, Dr. Bristol, Plain Full Cheek, (same thing as the other snaffles - chewed and tossed her head, and pulled like crazy. I also had very little control) Mylar D ring with hooks…The last bit is the one that she goes the best in, but it’s still not perfect, and will still fuss with it - however, I do have my power brakes and steering back for the most part. She still can get strong, but I would rather have that, then her get behind the bit.
I have also used a SidePull, and as long as we are just doing a walking Trail Ride, she is wonderful in it. Anything more and I lose the brakes and steering.
Any ideas?
