What is one of the main functions of the frog in a horse's hoof?

The main function of the frog in a horse's hoof is shock absorption during movement. The frog is a V-shaped, elastic structure located on the underside of the hoof that acts as a natural shock absorber. When a horse walks, trots, or gallops, the frog compresses and spreads out under the weight of the horse. This compression helps to dissipate impact forces that occur during footfall, protecting the sensitive structures within the hoof and contributing to the overall comfort and performance of the horse.

In addition to this primary function, the frog also aids in promoting circulation within the hoof. As it flexes and adapts to the ground surface, it creates a pumping action that helps to facilitate blood flow back up the leg. This is critical for maintaining healthy hoof function and overall limb health.

While the frog does contribute to the structural integrity of the hoof and plays a role in shoe retention by providing a surface for the shoe to rest against, these are secondary functions compared to its primary role in shock absorption. Understanding the role of the frog helps in recognizing its importance in equine welfare and hoof care practices.
