What is the vomeronasal organ, and what does it do?

The vomeronasal organ, also known as Jacobson's organ, is a specialized chemosensory organ found in many animals, including dogs. Located in the roof of the mouth, it is dedicated to detecting pheromones, which are non-volatile chemical signals. These pheromones transmit vital social, reproductive, and emotional information between animals, often below conscious awareness, influencing behaviors like mating and territorial marking.
