Horses are very different from humans when it comes to sleep, and it is very rare to find your horse truly asleep. But what happens when a horse does sleep and do horses sleep with their eyes open or closed?
So, as we have learned, when a horse is in a deep sleep he will have his eyes tightly closed. This is essential to get a good-quality restorative period of sleep. However, if a horse is in a light sleep then he may have his eyes open or partially closed.
