Quote Bobthebuilder - "So my question is- is it possible to do dressage properly in a bitless bridle?"
Answer - Yes it is possible - its as possible to do as it is in a bitted bridle - if you are the right rider.
Similarly, maybe some horses just don't like head pressure?
She is a sensitive little lady- and hates pressure of any kind, if you try to hold on to her in any way when she doesnt want to- she will flip out. Not due to bad manners, but because she genuinely finds it scary.
She is also super sensitive around her ears in general.
I figured, because the mouth is so sensitive, to get the same effect not using the mouth, the pressure points would have to be kind of severe.
Not sure where discussing breeds came into this... Imo, all horses can do dressage, just as all horses can jump, all horses can race.
Wether they do it well or not... that's a different issue
And the dressage world is indeed unfair- I constantly get marked down due to my mares un flashy movements- even though she does everything I ask, flying changes, shoulder in, travers, etc. Unfair, but such is life. Of course, I don't really have any experience with drafts/ draft x's so I can't comment.
