My QH has gotten too good at playing with her bit as a nervous habit. If I hold her back from the group she will play with the bit constantly until I get her settled down.I have a single jointed bit on there now. What type of bit would you suggest using on her? I don't need anything harsh, she's very well trained and has a soft mouth. Thanks!
Maybe she needs to move, so instead of holding her back, keep her busy. So, if you want to hold her back, don't try to just dam up her energy, just let it flow into some sort of other work, like circling, backing sidepassing etc.
I agree with tiny. My horse is pretty nervous too, so... I just give her job to think about. You can also consider something like this: Mikmar Bit Company (last one with roller). But personally I'd rather have horse focused on me than on bit.
