Honey - I love this post that you made...
If I see a problem with my horse im not going to put some equitment on it for quick fixes!!
I don't punish my horse for showing me how she's feeling!
I take it and listen to it.... show or not.
I use lunge reins for the reason of helping her give to pressure with me off her and not have to be in her way and ruin her balence while she's trying to figure it out.
Chance recently was gaping her mouth open even with out much contact but even still she felt trapped so im still trying to figure her out and work with it. But I refuse to use a stronger bit... or tie anything down or closed ;)
