What are the main components of a horse's foot?

The main components of a horse's foot are indeed the frog, sole, and wall.

The frog is a V-shaped structure located on the underside of the hoof that plays a crucial role in providing shock absorption and promoting circulation within the hoof as the horse moves. It's essential for the horse's overall foot health and contributes to the natural functions of the hoof.

The sole is the bottom part of the hoof that provides a protective barrier against ground surfaces. While it is less supportive than the wall, it helps to protect the internal structures of the hoof and prevent foreign objects from entering.

The wall is the outer material of the hoof that offers strength and protection to the internal structures, including the sensitive laminae and the coffin bone. The wall supports the weight of the horse and helps maintain the overall shape and integrity of the hoof.

In contrast, the other options include components that are not primary parts of the horse's foot. For example, the hoof is a general term for the entire structure of the horse's foot, while fetlock and pastern refer to joint areas above the hoof. The crown, heel, and toe can also describe parts related to the hoof, but they do not encapsulate the essential components as clearly as the frog, sole
