Horses are herd animals and have a need to socialize with other living beings. In fact, according to a behavior specialist, it is essential for their well-being and survival. On the other hand, horses that are isolated can face serious health problems.
Studies show that horses can experience acute stress when they are isolated from other horses during daily routines such as training or transport. Prolonged stress can be induced by long-term transport, moving to a new stable, or during stall rest.

You've probably heard a horse call for its companion when it is taken away from the herd.
According to behavior specialist Robin Foster, horses are social animals with a basic need to form relationships deeply ingrained in their nature. Horses are prey animals, and from that perspective, it's much riskier to be alone than in a herd.
Horses form strong bonds with each other. For the same reason, it is more stressful for a horse to be taken away from the herd than if it generally stands alone.
Social isolation affects behavior, physique, and brain activity in many animal species. Studies show that isolated animals generally have increased respiration, heart rate, and they sweat more. Additionally, they often show abnormal memory when it comes to fear, reduced mental flexibility, and an increased flight response.
Horses react strongly to being isolated. One of the things affected is the sense of pain. A 2017 study showed that horses react more strongly to pain if they are isolated than if they are with other horses.
If your horse needs to be alone for a period due to injury or illness, there are several measures you can take.
Expose the horse to being alone in small doses. Start with short sequences of trailer training, or let the horse be alone for short intervals. Training in small steps helps prepare the horse for alone time in a gentle way.
Horses mirror how other horses feel. Therefore, it might be a good idea to have a calm companion nearby. In fact, it doesn't have to be another horse. Humans can be just as helpful. Studies show that the horse's heart rate increases when it is taken away from a friend, and it decreases again when the friend returns.

Sensory and mental stimulation can help in situations of social isolation. It can be specific smells, sounds, and activities that stimulate the brain. Additionally, mirrors have been shown to be useful in transport because they give the horse a feeling of not being alone.
If possible, it is advised by Robin Foster to avoid isolating horses as much as possible. Or at least gradually acclimatize them to it if you find yourself in a situation where it is necessary.
