Right now I ride my mare in a regular wonder bit, and I know that it puts poll pressure on her, but what else does it do? I also know it causes her to raise her head, which I don't like.
Do all gag bits work the same? Such as these ones:
Smooth Jr. Cowhorse bit
I would like to stop riding her in the wonder gag bit. Would it be better to retrain her in a full cheek snaffle or something?
