And also, I need help on curb chains. I know my old trainer use to put them on her, does it help with leverage, or control? And I need info on how to use it, like tightening it up or however. I want to know the ost I can, so she has the most comfortablest bit, and isnt in and discomfort. My old trainer use to put the curb chain so tight, it would leave a mark on her :/ Deffinently NOT putting it that tight on her again, he didnt know what he was doing anyways, hence why I moved her a long time ago to the current one, lol.
