In the wild, as well as in domestic care, horses will show affection to one another by sharing breath with one another. Horses will put their noses together and then share the air.
Use of smell
Horses greet each other by smelling, and shake hands by sniffing noses. Horses smell people, objects, and food to determine whether, good, friendly, or obnoxious.
Why do horses touch noses and squeal? Squeals often occur when unfamiliar horses meet, or when one violates the space of another, especially when there's an important resource at stake, such as food. Much like humans, horses sigh as a means of releasing tension.
There are a few different ways that horses can deliver a nudge. One is by using their nose to push on you. This can be a way of showing affection or a sign that the horse is impatient and wants you to move out of the way.
Horses prefer to be rubbed and stroked over being tickled or slapped, and they often don't want rubbing on sensitive areas like the flank, girth, belly, nose, ears, and legs. Several studies observed horses acting calmer during rubbing or stroking compared to patting.
Affection for Other Horses
It is also very common to see horses grooming each other; mostly itching each other's backs, shoulders, and withers. They will also rest their muzzles on each other's backs. Just like as they call to you when you arrive to see them, they call and whinny for each other.
Stallions frequently aim to attract mares by repeatedly biting their rear regions, sides or shoulders. They also often smell mares' bodies. Mares often react defensively by screaming, kicking and biting back. This behavior often lasts for days at a time.
4- Many horses like to be rubbed on the neck, shoulder, hip, or on the chest. Some horses enjoy having their heads and ears rubbed. Horses often groom each other on the whither, so this would be a good place to try too.
Typically, a horse bites someone as a sign of aggression. However, in some cases, a horse can bite you in a playful manner or even as a sign of affection. Although this can seem sweet at first, any type of biting should be immediately discouraged.
Squealing and roaring
A high-pitched, piercing squeal is also heard from horses in some situations. It can be a sign of anger and exuberance, but it can also be a warning.
Affection in Horse Terms
Kissing and hugging are human ideas of affection. Horses do “spar” (play fight) and bite at the lips, but that's even more of a reason not to kiss them there. Keep your horse's lips away from your lips. You don't want him to think you're playing and be bitten.
Horses have two basic forms of communication–vocal and body language. The more sophisticated of the two by far is body language. With a mere look, a flick of the ears, or a turn of the head, horses can communicate to each other and to us, if we learn to understand their body language.
You might think it strange or scary but the horse may be trying to say hello to you. When two horses meet each other for the first time, they usually stand nose to nose breathing into each others nostrils. Some (not all) horses try to do this with humans.
Some report you should use soft eye contact when dealing with horses, meaning you can look at the horse but also keep a wide field of view. Other trainers indicate hard contact is preferred to establish your dominance over the herd.
It really depends. They may show signs of sadness, much like when they leave a favorite herd mate. On the other hand, if you weren't that close they will likely have no emotional response to being sold. If they do appear sad, it's only time before they get comfortable in their new home and let go of those feelings.
Another good spot is the back and the cheeks and forehead. Be sure to stay away from the sensitive areas of the horse like the eyes, ears, muzzle, and belly of the horse. While some horses might be OK with you petting these areas, many are sensitive and won't like to be touched there.
When a trained horse becomes frustrated with the rider, the signs may be as subtle as a shake of his head or tensing/hollowing of his body, or as blatant as swishing the tail, kicking out or flat out refusing to do what the rider asks.
Horses stomp to indicate irritation. Usually, it's something minor, such as a fly they're trying to dislodge. However, stomping may also indicate your horse is frustrated with something you are doing, and if you don't address it, he may resort to stronger signals.
Horses can read human facial expressions and remember a person's mood, a study has shown. The animals respond more positively to people they have previously seen smiling and are wary of those they recall frowning, scientists found.
If a horse is grazing in a field and they come towards you when you are around you can be sure they like you. Horses that follow your movements in their presence show they are focused on and give you 100% of their attention. If your horse follows you around when they see you, they consider you as a friend.
Horses, as well as cats, rhinos and hedgehogs have this as a response to help their sense of smell. Raising their upper lip increases the flow of air through their nostrils which widens the scent openings behind their teeth on the upper palette.
