Has a sense of smell more developed than its senses of sight and sound
Horses have an extremely large head with well developed eyes, ears, and noses.
They have the largest eyes of any land mammal with a specially shaped retina that is structured so that they can view both their feet and distant objects with the same sharp eyesight. Often going unnoticed beside such well-known abilities is the horse’s superb sense of smell. [5’06″/Subtitles: Japanese, English]
