My moms 20 year old Thoroughbred mare who LOVES to run. She has begun to be a little snot and has begun running through the bit. She used to be soft enough to ride in an egg-butt snaffle but when she wants to go home, she wants to go home. So, we tried riding her in a tom thumb but she does not like the combination of leverage and a broken mouthpiece and my mom absolutely dislikes tom thumbs she just does not like the way they work. When Dixie is frustrated, confused, or being pulled on too much she will flap her bottom lip and kind of pin her ears. She did that CONSTANTLY with the Tom Thumb but with the EB she stopped doing that but then started running through the bit. We tried riding her in a med/low port curb with about 5" shanks and she did great but then started running through that even, so we tightened the curb strap and she started behaving a wee better but her started flopping her lip again and pinning her ears and doing her back up as soon as pressure was applied, so we loosened it a notch again, and lost control. So we thought maybe since she does better in a solid mouth piece, we will try that on a snaffle. So we got a D-Ring snaffle with a Mullen mouth piece. She ran through that as well.
It is NOT a pain issue. She is ridden in either a custom fitted saddle which was actually made from a mold of her back, or bareback and is the same either way. Would her teeth be the problem? The vet said they could be done, but it is not really effecting her.
What bit should try on her? We've gone back down to total groundwork, ground driving and she does SPECTACULAR until your on her back. She is OK int he arena and it's like getting into a battle with heck anywhere else. It's not a training issue, its a disrespect issue. We have tried join up with her, and Parelli and have not seen a change in her at all so I'm totally stumped.
I want her to be soft without used a twisted wire or corkscrew. I thought of a kimberwicke, what do you guys think?
Please do not be rude or critical, I'm asking if a change of bits will help and if so what bit should we change to, or if there is something we can do with the bits we have to help. We have a trainer that was helping us with her but she thinks we should use a twisted wire or corkscrew and we do not want to.
