What is a "hoof"?

The hoof is a tough and hard outer covering found on the lower extremities of certain animals, particularly ungulates like horses, cows, and deer. It serves as a protective structure and supports the weight of the animal, allowing for locomotion and stability on various terrains. The hoof is composed of a dense keratinized material, similar to human nails, and is divided into distinct parts, including the wall, sole, and frog. The hoof plays a vital role in the animal's movement, enabling it to graze, run, and navigate its environment effectively. Regular hoof care and maintenance are essential for the overall health and well-being of the animal.
