When my qh had a deep cut to the frog couple winters back I called my farrier very next morning (I found it out night before). He came out, cut off what was already cut, cleaned, put medication, and wrapped.
I kept cleaning it with the iodane solution, putting koppertox once/day (sometime at night, sometime in morning), and then wrapping the hoof with bandage and duct tape/Gorilla tape for another week - week and half till she grew some of it back. Not fun, of course, but I rather keep it clean.
