I didn't get to ride Nina today but I turned her out to run around for a while. She was still very slightly off but MUCH happier and moving easier. I am tempted to put something on that hole to toughen it up but my farrier asked me not to because he doesn't know what it is or what caused it. He thinks it would be best to leave it alone and see if it gets better or worse. I think that is a good idea and I tend to go along that path anyway.
