So we are mostly just waiting out the winter. We are having a fairly mild winter, Nina is gaining weight, but her behavior has leveled off, no progress. She is still spooky, even with me, and the few times that I tack her up to lunge she is willing to go to war over every bit of it.
I have checked out the trainer and I am very impressed. He is very low key and confident and doesn't believe in fighting with a horse. So just waiting for spring.
