On this page, you’ll explore key facts about horses—from anatomy and senses to behavior and long-term care. Learn how horses use flight responses and body language to communicate, and why their eyes are the largest of any land mammal. You’ll also connect day-to-day care, like daily forage needs and parasite control, to health indicators such as heart rate and breathing at rest. Then we’ll look at popular breeds and how racing shaped modern interest in horses.
