The search term "mleming" appears to be a misspelling. The correct term is flehmen. Flehmen in dogs, as in other animals, refers to a specific behavior where they curl back their upper lip, exposing their front teeth and gums, and then inhale. This action facilitates the exposure of the vomeronasal organ to scents or pheromones. The vomeronasal organ, also known as Jacobson’s organ, is a chemoreceptor that detects heavy, moisture-borne odor particles and is useful in the process of communicating chemical messages.
Why Do Dogs Flehmen?
Dogs flehmen to enhance their sense of smell, particularly for detecting pheromones and other scents of interest in their environment. By curling their upper lip and inhaling, they open their vomeronasal organ, allowing them to better analyze scents and gather information about other animals, potential mates, or their surroundings.
What Does Flehmen Look Like in Dogs?
Flehmen involves a dog raising its head, wrinkling its nose, and curling its upper lip to expose the front teeth. This creates a facial expression that might look like a sneer or a grimace. The dog then inhales deeply through its nose, drawing scent molecules into the vomeronasal organ.
Which Animals besides Dogs Exhibit Flehmen?
The flehmen response isn’t unique to dogs. Many other mammals, including horses, cats, ungulates, elephants, and bats, also exhibit this behavior. Male ungulates, cats, elephants, bats, and some other mammals facilitate access to the vomeronasal organ by curling the lips and exposing the upper teeth, with the nostrils closed. It’s a widespread adaptation for enhancing chemoreception across the animal kingdom.

Why is flehmen called Jacobson’s organ?
The flehmen response involves the vomeronasal organ, also known as Jacobson’s organ. This organ is named after Danish anatomist Ludvig Levin Jacobson, who discovered it in 1811. Jacobson’s organ is a specialized chemoreceptor that detects heavy moisture-borne odor particles, facilitating the perception of chemical messages.
What is the purpose of the vomeronasal organ in dogs?
The vomeronasal organ (VNO) in dogs is primarily involved in detecting pheromones and other chemical signals. Unlike the main olfactory system, which processes general odors, the VNO is specialized for detecting non-volatile compounds. This helps dogs communicate, find mates, and understand their environment through scent.
How do snakes use their tongues to flehmen?
Snakes utilize their tongues to collect scent particles and transfer them to the vomeronasal organ. Since the snake’s vomeronasal organ is isolated from the nasal cavity, environmental chemicals can only enter via the mouth. The tongue flicks in and out, trapping odor molecules in its salivary coating, which are then transferred to the opening of the vomeronasal organ.
In summary, flehmen is a fascinating behavior in dogs and other animals that enhances their sense of smell and helps them gather important information about their environment.
