He has never been a pull back horse and I am hoping he will come through this. It started when the farrier got after him in the cross-ties. Anyway, he sits back and he seems like he is passing out. I have to make him come to and hope that he doesn't come out of it thrashing.
Any insight on this issue would be very helpful. He is a 16.3 hand 3 year old TB, never raced started as a yearling race horse prospect. Really pretty reasonable horse.
