I was at the barn yesterday and was talking to one of the boarders about her horse's feet. Her horse has four white feet, and on the outside of the hoof(is this called the wall?) there are purple blotches that look almost like bruises. I have seen bruising of the frog and the underside of the hoof, but never anything on the outside like this one has. She said it only happens during the winter when its cold. The horse does not appear sore and has front shoes on.
Just wondering what could cause this?
