I have had my mares teeth filed and she has had her wolf teeth out so no problems there
After that I rode he rin her normal bit (which before the teeth she was fine in) its a hanging cheek french link, she was also in a plain cavasson noseband, when trotting and if you applied a bit of pressure say a half halt or a sign to walk she would throw her head up and open her mouth. So I put a flash on, she was better had more brakes actually too much brakes only a little pressure and she would come to a dead stop, she would still toss her head when trotting evan if I didnt have contact, I tried pushing her on to get her out of it that didnt work.i showed my friend what she done all I done was a little pull nothing much at all and she shock her head so we agreed to change the bit.
Changed it to a eggbutt snaffle today and took her into the school again with the flash on too much brakes way too much, tossing her head in walk trot and violenty in canter that much I was actualy scared and nearly got off.
Im at a dead end now, although I had her in a bitless (german hackamore) when I was waiting for her teeth to come out and healing she was ok in that, now do I put her back in it or is there anything else I can try.
Bear in mind she is only rising 4 and very soft mouthed
