Just wondering if I should be worried about a small chunk out of my horse's hoof... She isn't lame and the farrier only came last week, I'm not sure if it was like it when he came though. I have poked a hoof pick in the hole and it isn't sore at all so I'm assuming the sensitive part isn't exposed. Its near her heel because a few months ago she cut the coronet band so I was expecting a piece of hoof to fall out eventually. I'll post some pics if you like but its in a kinda hard spot to take a picture of so they may not be the best quality.
EDIT: same sort of thing as northernmama's post, only its not that bad!
