She is a very forward horse, and she also works in a very hollowed outline with her head in the air. I want to try and prevent her from lifting her head so much so that she doesn't develop an ewe neck.
What would you suggest I do about this? Running martingale? Riding with shorter reins and driving her into the contact to get a shorter frame? Or riding with looser reins and driving her forward into the reins for a longer frame? Please, I need help here, as she really needs to build some muscle on her top line.
I also don't want to force her into any frame, I want her to develop her own frame where she can hold herself instead of relying too much on my hands BUT still keeping her at a respectable speed.
Below are two pictures of her, just so you can see her top line. The first one is a fairly recent one showing her neck. The second one was taken last year September. She is the horse on the far left.
Any advice is appreciated.
