Horses often display what is commonly mistaken for a smile – known as the flehmen response – in various forms. Their lips will move while opening and semi-closing their mouth to take in any new smells or tastes they encounter.

Horses display this behavior when they enjoy something, such as being scratched or rubbed. Horses may also show their teeth if they feel any pain.

Flehmen response

Ever seen a horse light up their face when they detect an unfamiliar scent? This phenomenon, known as the Flehmen response, can also be observed in mammals, reptiles, birds and amphibians. Cannibalism is an instinctual response to certain smells and involves animals licking their lips while baring their teeth to push deeper into their nasal passages where it can be better assessed by their vomeronasal organ. This organ serves as a chemical receptor for moisture-borne odours that have come in through airways or from inside of our mouths, sending these scents directly to our brain via an accessory olfactory bulb and opening two small ducts on the roof of the mouth called Nasopalatine Canals which help transport them.

Reacting in such ways does not signify aggression and horses don’t actually smile when showing their teeth; rather it is used to communicate to other animals that they want to smell something specific; horses often show their teeth when sensing a scent like that of other horses or hay, creating a very distinctive and fascinating form of communication between their species.

Newborn foals can be quite endearing when they show their teeth for the first time; however, as they mature into fillies they may show them less often.

Feeling happy or sad

Horses tend to bare their teeth when in a happy or positive state of mind, or when stressed out or anxious.

Horses typically show their teeth when eating as part of the process. They will also bare their teeth when trying to investigate a scent or object more closely.

When horses are content they will often neigh with open mouths and closed eyes, creating the appearance of smiling. But it is the sound of their neigh which matters more; short whinnys may indicate joy or fearfulness respectively.

There are various techniques for teaching horses how to respond on command by making use of treats held above their nose while tapping his upper lip with your index finger, saying “smile”. Alternate these actions until he shows it on cue. Another effective method for teaching this behavior would be using a clicker; using it will teach your horse that showing this behavior leads to rewards, encouraging him to repeat it independently.

Horses have a remarkable capacity to remember facial expressions they observe on human faces and are affected differently depending on whether the expression was smiling or frowning. Studies have revealed that horses spent more time looking at models with frowning faces with their left eye while viewing happier models with their right eye – this behavior has also been observed among wild crows who hold grudges against people they have had bad dealings with for an extended period.

Disliking something

When horses do not like something, they often exhibit teeth-baring behavior accompanied by parting their lips and sticking their tongue out, as if trying to rid their mouths of its taste. This behavior may be seen when dewormed horses or those averse to certain treatments and medicines are dewormed or when scared or nervous horses show this response.

If this behavior continues, however, it could indicate pain or discomfort and is advised that an appointment be scheduled with your veterinarian immediately.

As well as showing their teeth, horses will lick and chew at the ground when stressed or uncomfortable, sometimes even bucking and kicking when feeling threatened or scared.

People often struggle to comprehend horse’s behavior, misinterpreting it for aggressiveness or threats when this is not always the case. Horses are highly intelligent animals that often demonstrate emotions through subdued behaviors.
