My favorite recipe for hoof greebles(whatever kind) was always a betadine scrub and epsom salts paste. Apply to sole/pack it in as needed then lay a piece of 4" gauze or something. Vetwrap the hoof then apply a duct tape boot. Or you can use a hoof boot if you have one. I like the duct tape boot for this. To make one lay strips overlapping each other to a size that will cover the sole and wall pretty much.. Wrap more around it to hold on and leave it for a day or 3.. The paste will draw out and dry up greebles.. *greebles are whatever is bugging the hoof, thrush, abscesses etc..
