New horse bought right before hard dreadful winter, she has developed a habit of running down hills like a bowling ball. Starts at walk for a short bit then it’s like her big ass pushes her and she books it down. I have tried a one rein turn around and start again… turn around, start again. She doesn’t back well but we’ve tried that too. Does it in open fields, woods trails even with horses in front of her she will push through or go to side. It started in English saddle, but even switched to full western and one time it was better, but second time its worse now. Other than the down hills she is fine on the trails. She will pass horses and wait at bottom.
She doesn’t do this if you are leading her.
I sit back, sit deep, and if I try to hold her back on reins she will fling and shake her head and continue with a bent neck, unless I fully turn her around.
Any ideas? I am trying different bits as well.
Tired of circling down hill.
