Sorry I haven't replied in so long, I've had my hands full! Ok, her trainer did come and she put on quite a show! She pranced, turned, stopped on a dime, backed up, and anything else he asked. He showed me the difference in how she was trained to respond vs how I was handling her. I've been able to ride her everyday ans she has been amazingly patient as I try to master the techniques.
As for her medical condition, he says her vision is actually better than it was years ago when he worked with her and it was caused by malnutrition when she was younger. I know she was taken to the vet in May and they did blood work because I have the paperwork but exactly what was done I don't know. I've contacted 2 vets, 1 of whom I didn't like at all (he had the personality of a salt block) and the other I liked quite well but haven't asked him to come out yet.
I would love to post a pic of her....but I can't figure out how! ?!?!
