It's a conditioner for hooves. I was just wondering because I noticed that Sissy's hooves are really dried out and I need something to use. I found a tub of it in the bottom of my 'horsie stuff box" lol.
Try a good diet, a hoof supplement and proper exercise/environment. You cannot fix hooves by plastering stuff on the outside of them. People in my barn use all kinds of hoof dressings and like to put them on my gelding when I'm not there. The smell and nasty, greasy hooves left behind are a dead giveaway.
