What is the Difference between Horses, Mules, and Donkeys?

Difference Between a Donkey, Mule, and HorseAt first glance, horses, donkeys, and mules appear similar, yet these animals are a diverse bunch. They do share common similarities though, which is why they may often be confused for each other. To obtain a better understanding of these three mammals, it is worth taking at look at the many specific differences and similarities. Explore the different physical characteristics, habitats, and uses for these widely used and admired animals below.

Physical and Genetic Differences

It should only take you a second to realize that the horse, donkey, and mule don’t exactly look the same. It may be easy to spot a horse, but sorting out the difference between a mule and donkey can be a challenge!


Horses share many similarities with the other creatures on this list. They are all four-legged, hoofed mammals. Horses tend to have shorter ears and longer faces than the other mammals. The hair on their manes and tails is soft and flowing as well. Many people notice as well, that horses are herd animals and tend to spend their time in large groups. Horses are often flighty animals and run from any perceived danger. The genetic makeup of a horse is specific to them as well. Horses have 64 chromosomes.


Donkeys have visibly longer ears than horses and mules. The hair that makes up their manes is stiff and bristly, noticeably rougher than other creatures. Their hooves are smaller as well and they have a flat back which can often not hold a saddle. Donkeys are less social and tend to form bonds with only one other of their kind. They are also more sedate creatures, difficult to spook. Donkeys have fewer chromosomes with only 62.


A mule is the result of a horse that has been bred with a donkey. Mules are generally sterile, meaning that they cannot be bred with each other in most cases. They also have 63 chromosomes. In appearance, mules may look very similar to donkeys. They also have stiff hair. Much like donkeys, mules are strong animals and tend to have calmer personalities. They are very vigorous animals which is why mules may be often used as pack animals.

Natural Habitats

Because the mule, donkey, and horse have all been domesticated, it is rare that you will ever see a wild one unless you find yourself in remote parts of the world. But it wasn’t always that way.


Since horses evolved from a small creature, they were actually one of the first species to be domesticated. Although there are some horses which do survive in the wild, they have primarily existed as companions or work horses. Horses do fairly well when left to their own devices. They do need a steady water and food supply and tend to stay in herds where they can protect each other.


The donkey is actually adapted to desert lands. Since they are hardy animals with decreased water needs, they do well in desert environments. They also tend to spread out over large areas and can defend themselves by biting or striking other animals.


Although mules can survive in a similar environment as donkeys, they do not have a natural environment since they are the offspring of a donkey mating with a horse. When in the wild, donkeys tend to form pairs or very small groups and can live in desert areas or areas with a limited food and water supply. Since they have a curious and playful nature, they tend to seek out other animals or humans and are rarely found alone.

History of Uses

Donkeys, Mules, and Horses have been used by humans for thousands of years for transportation, industry, farming, entertainment and general labor. It is interesting that each of the below animals has a distinct difference among them when it comes to how they became such an important part of human history.


Horses have a huge range of uses, but they were primarily used as transportation for humans, racing, or labor. On farms, horses could be used to pull plows and perform other tasks. They were also used for sport and still perform in races today. Because they can hold a grown human well, horses are particularly useful for transportation and can carry a human for long distances. Their personalities and appearance made them a popular part of everyday life.


As a member of the horse family, donkeys have been used as primarily working animals for at least 5000 years. There are millions of donkeys throughout the world. Donkeys have been found to be intelligent, cautious, and playful, which made them perfect for both companions and workers. As fairly strong animals and lacking the speed of the horse, they were used by people around the world to help with carrying and other tasks of labor primarily in areas where there was a lack of water.


Mules were traditionally used as farm or pack animals, especially useful on mountain trails. . Their strong stamina made them a practical animal for a variety of tasks. Mules also eat about a third less per day than a horse of the same size. They also have decreased water needs, meaning that they can work longer without needing as much water or food. They also work well on basic forages like grass hays, practical when foods are scarce.

So which is your favorite? The Donkey, Mule or Horse?

  1. It looks to me like the donkey and mule pictures are reversed. The picture that states the animal is a mule has slightly wider spaced eyes and the gray coloring with the brown stripe down it’s back. That would be a donkey. Of course, there can always be exceptions, but if selecting pictures for comparison, I would think what is typical would be chosen.
