Help!
My mare runs through the bit when out hacking- only when in company and going fast. She just ignores any pressure at all, snatches and grabs at it. If you go the opposite approach and loosen the contact, give her her head etc she gets faster and faster.
In open space it's not such an issue as she does stop when the group stops. The problem is on bridleways, really. She's totally mindless and just charges faster and faster after the ones in front, regardless of what branches and overgrown things are hanging in our way. I've nearly been decapitated a good few times!
She's awesome in the school - very responsive to seat and voice, works in a light soft contact and not at all strong. Unfortunately, once She's following another and going faster than walk, all training related to seat and voice seems to vanish out the window. She just doesn't pay any attention!
I don't want to be hauling on her mouth. She's currently in a neue schule team up for schooling and standard French link for hacking.
Any ideas much appreciated.
