However, tacking up before a ride is becoming a battle of wills. At the moment it can take anywhere from 5 to 15 mins to get the bit in her mouth, and that's with a lot of coaxing. She clamps her jaw shut. I've never had a horse do that before!
So any advice on working with her to get her use to the bridle and bit? I've double checked the bridle, and bit, and tried different kinds, but she responds the same.
Any advice would be appreciated.
