Corona Hoof+Shield is a simple yet effective hoof care spray for use during the care of thrush, white line of the hoof and seedy toe. Hoof+Shield cleans and irrigates damaged hoof tissue where there is thrush, unpleasant odor, irritation and brittleness. Its non-caustic and non-staining formula is a favorite among horse owners, as it is very safe to use and doesn't stain. Hoof+Shield's targeted trigger spray makes it easy to reach every crack and crevice in the hoof. Formulated with revolutionary Microcyn(r) technology, Hoof+Shield is effective when used every 5-7 days, but is safe to use daily if needed.
