How Social Are Horses, Burros and Mules? Inside the Social Lives of Equines
Spend enough time watching a herd at Broken Arrow Ranch & Sanctuary and it becomes clear that there is always something happening between the animals.
A few horses gather around the water trough as if they are catching up on the day's news. One moves away and another follows. Friends graze close together. A mule quietly keeps watch nearby. Somewhere else, Jupiter drops to the ground for a good roll, continuing behaviors he first learned while growing up beside his mother, Beauty.
These moments can look simple from a distance. In reality, horses, burros, and mules have rich social lives shaped by companionship, communication, observation, and relationships that develop over time.
For rescued equines, having the freedom to form and maintain those relationships can be an important part of sanctuary life.
Horses Are Deeply Social Animals
Horses evolved to live alongside other horses. Free-ranging horses generally form stable social groups, often consisting of mares, their offspring, and one or more adult males. Within those groups, relationships influence where horses rest, graze, travel, and spend their time.
According to the MSD Veterinary Manual, mares form friendships, horses have established social hierarchies, and much of herd organization depends on relationships rather than constant fighting or aggression.
What's the Gossip Around the Water Cooler?
When several horses gather at the water trough, it can certainly look like a meeting.
Water, forage, shade, and preferred resting areas are all important resources within a herd. Horses pay attention to who is nearby, who moves first, where companions are heading, and what the rest of the group is doing.
You will sometimes hear people describe a herd as being controlled by one dominant lead mare. The real picture is more nuanced. Mares are central to horse social groups, but movement decisions may depend on circumstances and individual needs. The horse who is thirstiest or most motivated at that moment may be the one who starts heading toward water, with others following.
So perhaps they really are discussing where everyone is going next.
Herd Relationships Create a Sense of Security
For a prey animal, there is comfort in having other eyes and ears around.
A horse resting does not have to monitor every direction when trusted herd mates are nearby. Animals can graze together, rest near preferred companions, mutually groom, play, and respond to changes in the environment as a group.
Researchers and veterinarians also recognize that isolation can negatively affect horses. The MSD Veterinary Manual notes that horses require social contact for normal behavior and well-being, and that confinement or isolation can contribute to unwanted behaviors.
At Broken Arrow, this is one reason open space and herd life matter so much.
Many of our rescued equines arrived after experiencing neglect, displacement, uncertainty, or other difficult circumstances. Here, they are given time. They can move at an unhurried pace, choose where to graze and rest, and develop relationships with other members of the sanctuary herd.
That freedom creates room for trust to grow.
Burros and Mules Have Social Lives Too
Horses may receive much of the attention when people talk about herd behavior, but burros and mules are social equines as well.
Their social patterns are not identical to those of horses. Research involving mixed groups of horses, donkeys, and mules has found that the different equids can develop relationships with one another while still showing species-specific differences in how they interact.
Donkeys can form particularly strong bonds with companions. UC Davis veterinary programs even use bonding assessments when determining appropriate groups for donkeys, taking both their medical and social needs into account.
The Watchful Mules of Broken Arrow
At our sanctuary, we have also seen another fascinating dynamic.
Our mules often keep a close eye on the horses around them. We have observed them watching over their equine companions and responding quickly when something catches their attention.
That watchfulness contributes to the sense of security within our mixed herd.
Every individual is different, and we would never assume every mule will behave the same way. What we see at Broken Arrow, however, is a beautiful example of how relationships can develop between different kinds of equines when they are allowed to live together naturally.
For animals that once lived through uncertainty, having trusted companions nearby can become part of what makes sanctuary feel safe.

Equines Learn From One Another
Social life is also one of the ways young equines learn how to navigate their world.
Foals watch their mothers and interact increasingly with other horses as they grow. Through play, grooming, movement, and observation, they develop skills that will become part of adult social behavior. Veterinary behavioral research recognizes these early social experiences as important to normal development.
We see a wonderful example of this relationship in Jupiter and his mother, Beauty.
Jupiter's Horse-Style Spa Day
Anyone who has watched Jupiter roll enthusiastically in the dirt knows that he takes his spa days seriously.
Rolling, sometimes called dust bathing, is a normal behavior seen across the equine family. Research on horses and mules has found that rolling is associated with self-care and comfort and may also contribute to thermoregulation. Horses and mules can even show different preferences for the surfaces they choose when rolling.
It may help an animal scratch places that are difficult to reach and work dust through the coat. It also gives equines an opportunity to express a deeply ingrained natural behavior.
And Jupiter has had a good teacher.
Learning From Beauty
Beauty arrived at Broken Arrow with Jupiter when he was still a colt and has long carried herself like the matriarch of the sanctuary.
Growing up alongside her meant Jupiter had the chance to observe an experienced adult horse doing all the ordinary things horses do. Grazing. Resting. Moving with the herd. Responding to other animals. Finding a satisfying place to roll.
Some lessons really are learned simply by watching.

Friendship Can Be Surprisingly Specific
Equines do not necessarily treat every member of a herd exactly the same.
Horses can develop preferred companions. Some regularly graze together. Others stand near one another while resting or seek each other out for mutual grooming.
Those relationships may become especially visible when a herd member is moved, when a new equine arrives, or when one animal chooses repeatedly to remain beside another.
Burros can form close pair bonds, while mules living in mixed groups may develop relationships with horses, donkeys, or other mules.
For caregivers, noticing those preferences matters.
At a sanctuary, good care involves understanding more than what an animal eats or when the farrier is due. It means knowing who tends to stand beside whom, which animals feel comfortable together, who needs more personal space, and how herd changes might affect each individual.
Why Social Freedom Matters for Rescued Equines
A beautiful pasture certainly gives horses room to move, but the value of sanctuary extends beyond acreage.
Freedom includes the ability to make everyday choices.
A horse can decide to graze beside a longtime companion. A burro can seek out a bonded friend. A mule can stand watch while the others relax. Jupiter can find exactly the right patch of dirt for an afternoon roll.
These are ordinary equine behaviors, and that is precisely what makes them meaningful.
For animals whose lives may once have been controlled by circumstances outside their control, ordinary days can become something extraordinary.
There is time to graze. Time to rest. Time to make friends. Time to learn from one another. And time to simply be an equine.
Frequently Asked Questions
Do horses need other horses?
Horses are highly social animals and generally benefit from appropriate social contact. Their relationships can include preferred grazing partners, grooming partners, playmates, and other members of a stable herd.
Do burros bond with other animals?
Yes. Donkeys can form strong social bonds, including close pair relationships. Their social needs should be considered alongside their physical and medical care.
Can horses, burros, and mules live together?
They can. Mixed groups need to be managed thoughtfully because each animal has its own personality, history, nutritional needs, and social preferences. Research has documented social relationships among horses, donkeys, and mules living together.
Why do horses and mules roll in the dirt?
Rolling is a natural equine behavior associated with comfort and self-care. Research has also found evidence that it can help horses and mules regulate body temperature, particularly after exercise.
How does herd life help rescued equines?
A stable social environment can provide companionship, opportunities to express natural behavior, and the reassurance of familiar animals nearby. At Broken Arrow, herd relationships are one part of a larger approach that includes open space, individualized care, good nutrition, veterinary support, and lifelong sanctuary.
Give Them the Freedom to Belong
At Broken Arrow Ranch & Sanctuary, rescue is about creating a home where horses, burros, and mules can live with dignity, choice, companionship, and peace.
From Beauty teaching Jupiter the rhythms of herd life to our watchful mules keeping an eye on their companions, these relationships are woven into daily life across the sanctuary.
