What is the main result of properly using a hoof pick?

Properly using a hoof pick primarily results in the prevention of hoof-related infections. This tool is designed to remove dirt, debris, and stones that can accumulate in the horse's hooves. If these materials are not removed, they can lead to conditions such as thrush or abscesses, both of which can cause pain and lameness in the horse. Keeping the hooves clean promotes overall hoof health and allows for proper hoof function, which is essential for a horse's well-being and performance.

In contrast, while factors like speed of riding, ride smoothness, and coat quality are important aspects of horse care, they are not directly influenced by the use of a hoof pick. Thus, the correct answer highlights the critical role that maintaining clean hooves plays in preventing infections and ensuring the horse remains sound and healthy.
