Chevy and I have been working in dressage the past 3 years. The end of last year he was finally rounding his head and looking decent, but he was very flat and not propelling himself from behind. The past 3 months he has IMMENSELY began to propel himself, and he is moving and able to extend 3/4 the way and I am so excited! He has now, however, lost his beautiful head set! He either sticks it up in the air, looking like a unicorn or a pack mule, or he puts his head so far down, he has kicked himself in the face before!
I hold my outside rein and wiggle the inside with my inside leg pushing to bend him to the outside and he gives me the head set I want, but its only for a few steps and he throws it to the ground then tosses it in the air. I keep a consistent light contact on the bit (a snaffle) and when he does what I ask him to, I give him a light squeeze to step into what I'm asking, then I remove 1/2 the weight I was using to ask him to work with. Any advice/tips/or exercises I can do would be insanely helpful! Thanks y'all, have a good day!
