Powerful extra-strength gel formula dispensed from a squeeze bottle with a long flexible-tip applicator cap. Tip allows for the exact placement of gel along the horn rim and frog with no messy waste or run-off. Gel contains special medical dye that stains diseased hoof tissue and shows where to add more gel as the blue color fades. Use on nail holes, cracks and defects. Apply along horn rim, deep into the sulcus, under shoes and pads.
