If you are thinking of applying oil to a horse’s hooves, you can use sunflower oil or any vegetable oil to accomplish this. Horses’ hooves should maintain a natural amount of moisture. However, their hooves can become dry and brittle if the weather is hot, dry, or extra cold with little humidity. Horse owners may want to use coconut oil as well to help their horses avoid the brittleness in their hooves. Vegetable oils like sunflower oil or olive oil are a more cost-effective solution to this problem. You’ll need to mix your oils with lanolin, which will keep the moisture locked in upon applying it to horse hooves. You can also add some Aloe vera as well as essential oils. You will also need to boil the mixture.
