Kristina let Zing have too much room and he took advantage of it. Bill wants her to catch him before his head gets all the way up with the right rein by raising it up and bumping him and continue until he gives. It's about timing and persistence. Going up with the rein doesn't hurt him but does bother the horse enough to not want to be there. It really worked well. At the canter, if he tosses his head she is to bring him to the trot and bring the right rein up and as soon as he gives go back to the canter. He has to stay in motion. A lot of progress was made during the lesson.
The good thing about the work Kristina has done over the last month is Zing is not bracing against the bit anymore and he was round and cadenced in his trot. Zing pulls his tail to the left, but it's not a true wry tail as he can move it wherever he wants. Bill says his muscles are shorter on the left, so he wants Kristina to do modified shoulder in and half pass to the left to straighten those muscles. It made a lot of difference during the lesson yesterday, he was holding his tail straight about 30% of the time.
We are going again next week to keep the momentum going, but I can't afford Bill on a weekly basis, so after next week we will need to slow down!
It's very rewarding to have someone with such a high skill level to go to. And he is such a gentle man. I feel lucky to be able to go over there.
