Abstract: A liquid dispenser efficiently and effectively delivers a liquid treatment to any site to be treated that is situated in hard-to-reach recesses, such as grooves or cracks. The liquid dispenser can be used to deliver a liquid for treatment of hoof thrush in horses. The dispenser comprises a hollow body and a throat, a removable dispenser cap, a nozzle and a dome-shaped tip comprising one or more liquid dispensing orifices. Also disclosed is a method of treating hoof thrush in horses by dispensing hoof thrush treatment from the dispenser into the grooves and cracks of a hoof to be treated. The nozzle reaches into the groove or crack to be treated. The curvature of the dome-shaped tip allows the broadcasting of the liquid thrush treatment through the orifices into all areas of the groove or crack. Further, the shape of the tip discourages clogging with dirt.
