What is the purpose of the frog in a horse's hoof?

The frog of a horse's hoof serves as a crucial shock absorber during movement. This triangular, cushioned structure located on the underside of the hoof plays an essential role in assisting with impact absorption as the horse walks, trots, or gallops. When the hoof strikes the ground, the frog compresses, allowing for efficient distribution of pressure and reducing the impact on the bones and joints of the horse's leg. This not only helps in preventing injuries but also contributes to the horse's overall comfort and performance.

In addition to its shock-absorbing properties, the frog also has other important functions. It aids in circulation, as the compression and release stimulate blood flow within the hoof. However, the primary purpose directly tied to the question is its role in absorbing shock during movement.
