The Arabian horse is the oldest purebred horse in the world. The Arabian was the horse the Bedouin people (nomadic people) of Arabia as early as 3000 to 2500 BC. They were later introduced into Europe and throughout the world. All Arabian horses have black skin underneath their coats, except underneath any white hair. When these horses lived in the desert, the black skin would help to protect them from the hot sun. Horses see, hear and smell better than humans. Horses are very sensitive to touch. They can sense a fly landing on any part of their body and use their tail to flick it off. A horse’s heart beats 46 to 42 beats per minute. If frightened this can rise quickly to over 250.
