Horses Sleep Standing Up
Yes, horses can sleep standing up. They sleep lying down, too. Horses must lie down to achieve a full restorative sleep cycle for a minimum of 30 minutes per day to avoid sleep deprivation. There are many factors that influence a horse's ability to lie down to sleep and rest. These factors may be environmental, such as weather, available space, and comfortable bedding, or physical deterrents, such as musculoskeletal impediments (e.g., osteoarthritis).

Horses Can't Burp
That's right! Horses can't burp, at least not the way humans do. They can't vomit or breathe through their mouths like humans do either. A horse's digestive system is a one-way street, unlike cattle and other ruminants who regurgitate food to re-chew it. Although they have a pretty efficient way of processing the tough fibrous foods that make up their forage, this long, one-directional system can cause problems that result in colic.

You Can Estimate a Horse's Age by Their Teeth
While you can't tell the exact age of a horse by their teeth, you can estimate their age. Horses need proper equine dental care for their teeth, but sometimes a horse lives longer than the teeth do, so extra care is needed when feeding senior horses.

Horses Can Live to Be More Than 30 Years Old
One of the most common questions about horses is, "how long does a horse live?" The answer may surprise you—some can live over 30 years. Knowledge of horse nutrition, horse care, and veterinary medicine has increased. Because of this, just as human life expectancy has increased, so has equine longevity.

Horses Are Herbivores
Humans are omnivores, lions are carnivores, and horses are herbivores. The way their teeth are formed (grinding molars to break down fibrous plant material), the position of their eyes (on the sides of the face to be on the lookout for predators), and the type of digestive system they have are all typical characteristics of herbivores.

Horses Are Herd Animals
Horses in the wild live in small herds, and domestic horses feel more comfortable if they have companions, too. It can be quite stressful for a horse to live alone. Companionship for horses may be an equine stablemate or even another species such as a goat, donkey, or mule. Even a dog may become a suitable companion for a horse.

Humans Domesticated Horses More Than 3,000 Years Ago
Dogs may have become domesticated around 14,000 years ago. Cats became human companions about 8,500 years ago. Humankind's relationship with the horse began a little more recently, around 6,000 years ago, although some evidence has come to light that horses may have been domesticated even earlier.

Horses Are Measured in Hands
The standard measurement for determining the height of a horse is called a hand. One hand is equal to 4 inches. A pony is an equine under 14.2 hands. The only equines not measured in hands are miniature horses, which are measured in inches or centimeters.

A Horse's Resting Respiratory Rate Is About 8-14 Breaths per Minute
It's important to know the resting pulse and respiration rate of your horse. While the resting respiration rate of a horse can be as low as eight breaths per minute, that can quickly increase with work or distress. Learn your horse's resting pulse and respiration rate (TPR) so you can keep an eye on them in case changes occur.

Horses Are Not Native to North America
Every horse on the North American continent is a descendant of European horses. Even the horses that we regard as "wild" are actually feral horses whose ancestors escaped from captivity. Horses disappeared from the Americas more than 11,000 years ago, and there is ample fossil evidence that the horse's ancestors lived there prior to that.

A Baby Horse is Called a Foal
What is the difference between a filly, a colt, and a foal? It all depends on gender and age. Generally, a foal is a baby horse, but a filly is female and a colt is a male. After they are weaned from their dam, they are called a weanling. Horses remain fillies or colts until they are 4 years old.

The Original "Horse" Was the Size of a Golden Retriever
The original horse was no larger than a golden retriever. Diminutive Hyracotherium may have looked more like a small goat or deer than a modern-day horse. Hyracotherium lived during the Eocene Epoch about 50 million years ago.

Horses Are Extremely Intelligent
A horse can learn human words and remember you even if you’ve been away from each other for a long time, especially if you treated them well. Their memory is comparable to that of elephants. And, like dogs, horses can be trained.

Horses Can Only Breathe Through Their Nose
Unlike other animals, including humans, who can breathe through their nose and mouth, horses can only breathe through their nose. They are known as obligate nose breathers. This is something that horse riders and trainers should keep in mind while exercising their animals.

Horses Have Excellent Hearing and Vision
Horses have a strong sense of hearing, able to pick up sounds in the 55–33,500 hertz range, so they can hear things that humans (who can hear between 20–20,000 hertz) miss. In addition, horses can see very well, with a nearly 360-degree field of vision, and their eyes are larger than those of any land mammal.

Foals Can Stand, Run, and Trot Shortly After Birth
Unlike human infants who are helpless after birth, foals are able to get up and move around not long after being born. Within just one hour of birth, a foal can stand. Within the first two hours after birth, a foal can nurse.

Horses Have Fast Reflexes
Horses can react surprisingly quickly when they need to, especially since they are prey animals that have to protect themselves. Their reaction time (less than 1 second) is faster than a human’s, which is why you should know where to stand when near a horse to avoid getting hurt if they get spooked or feel threatened.
