Feb 17, 2022 · The reaction is often triggered by the smell of the newborn foal or the amniotic fluids that were associated with its birth. Although Geldings are less likely to exhibit the behavior than mature horses, any horse can be triggered by a new scent like a dietary supplement or feed ingredient.

The term “flehmen response,” also called the “flehmen reaction,” refers to a specific behavior shown by all equines at some stage during their lives. A horse that displays the flehmen response pushes out their neck, raises its head and rolls their upper lip back to display their teeth. While they do this, the horse will also inhale through their no...
It’s not to smile, they lip curl to get a better whiff. Curling the upper lip allows the horse to push the scent further into their nasal passage, where it is trapped and analyzed by the vomeronasal organ (VNO). This is why the flehmen response can show that a horse has detected something unexpected or interesting as opposed to a scent they are alr...
The vomeronasal organ, also known as jacobson’s organ, is a chemosensory structure found in many mammals. It’s surrounded by a boney or cartilaginous capsule that opens into the base of the nasal cavity. It is made up of two tubes (from the mouth and nasal passages) that lead to a sensory-lined chamber inside the organ. Chemical signals, like phero...
The word “flehmen” is German and means “to bare the upper teeth,” a rather fitting word for the “flehmen response!” In 1930, Karl Max Schneider, who was in charge of the Leipzig Zoo, was the first person to use the term in this way.
Horses have afantastic sense of smell. It is essential to their survival that they can quickly identify the right foods to eat, poisonous plants to avoid, dirty water, and predators for wild horses. Their sense of smell must identify foods that are safe and nutritious, such as grasses, hay, and shrubs. They must also be able to recognize poisonous ...
The horse’s olfactory system is the nasal structure that gives them their sense of smell. That great sense of smell mentioned above is thanks to a large nasal cavity. This part of their respiratory system is made of cartilage and a structure called turbinate bones. When air is inhaled, it stirs around the turbinate bones, causing the smell to be mo...
Stallions are the most common type of horse to show a flehmen response, most often after sniffing a mare in estrus, which means in heat. In other words, he is checking to see whether she is ready to mate, and these pheromones illicit the flehmen response. When stallions are in the presence of a mare in heat, they might flehmen several times an hour...
Yawning
A horse’s yawning can be misinterpreted as them having a flehmen reaction. A good way to tell the difference between the two is to look at the horse’s eyes. They will generally close their eyes when having a good yawn. Another straightforward example is their mouth opening wide during a yawn. When a horse has a flehmen reaction, their mouth does not open.
Champing
Champing or snapping can also be misinterpreted as the flehmen response. This is a typical behavior for young horses (particularly foals that have been weaned from their mothers) when meeting older horses. This is a sign of submission. They will stretch their head forward and lift their top lip while champing their mouth open and closed. It looks like they are chewing on the air.
Wiggling Upper Lip
When a horse wiggles their upper lip it could be confused for the flehmen response. Horses usually do this with their upper lip when they are getting a good scratch. They will lift their head and wiggle their lip in pleasure. They may also wiggle their lip to groom a nearby horse or person to show appreciation for being scratched or to initiate mutual grooming.
Yes,foals can show a flehmen reactionas early as one day old. Actually, the flehmen response is most common in foals during their first month of life. The world is a new and exciting place for them, and so are all the smells. If you have ever met a newborn foal, it isn’t uncommon for them to curl their little upper lip after smelling you. This smil...
Absolutely. The flehmen response can show signs of pain, particularly early signs of colic discomfort setting in. Colic is abdominal pain, which for horses usually originates in their gastrointestinal tract. Three common types of colic in horses are gas, impaction, and functional obstruction. The most common type of colic is gas colic, and thankful...
The word vomeronasal comes from the organ being close to the vomer bone in the nasal cavity. The Danish anatomist Ludvig Jacobson was the first one to describe the organs in 1813, so they’re sometimes also called Jacobson’s organs.
