Personally I feel like the rider has put too much emphasis on the position of her horses head. He/she is broken at the 3rd vetebrae? I think? And this indicates he hasnt moved into this position by working from behind. The amount of saliva produced indicates also to me that he is fighting the bit or trying to protect his mouth from all the pressure from his rider of keeping his head there.
I just wanted to see what you more informed dressage people thought, because I see SOOOO much of this situtation from people I know its quite shocking. These people are all at what I once though extremely well knowledged in dressage.... but it seems to me now their definition of dressage is where the horses head ends up.
Im not sure if I am allowed to post this picture, seeing as its not mine. But I thought seeing as it was from google it would be alright? I apologise if not.
