Hooves are the hard, protective coverings found on the feet of certain animals, such as horses, cows, and deer. They are made of a tough material called keratin, which is the same substance that makes up human nails and hair. Hooves help animals walk on various terrains and provide support and stability. The structure of a hoof includes several parts, such as the wall, sole, and frog. The wall is the outer part that bears weight, while the sole protects the sensitive inner structures. Proper hoof care is essential for the health of hoofed animals, as issues can lead to pain and mobility problems.
