 Call your vet or farrier if you have great concerns because it's possible that they have an abscess near that hoof. If you think about an abscess, okay, potentially open wound. And I wouldn't want to walk on it either. So you're going to want to make sure that if there is something going on, get it checked out. That may, in fact, lead to your vet saying, okay, now we've got to treat this. And if we're going to have to treat that, then one of those methodologies would be using a vaccine, which kind of leads me to a listener question.
