(I don't know that the horse had five legs; the one of the left is probably from a teammate. And a family member, by the looks of it.)
Which side of the right front shoe do you think he wears down most? I bet most Hoofcare and Lameness readers could draw a picture of what the bottom of this horse's right front looks like.
Draft horses are amazing. I think this is a draft horse, or possibly a Friesian. They often endure bad shoeing, no shoeing, lousy confirmation, cracked feet, ringbone, sidebone...and just keep going.
