The olfactory sense of canines are very sensitive; depending on the breed, it’s more than 40 to a million times more sensitive than the sense of smell of humans. Scent receptors lining the nose of dogs receive and decode various types of scents. Mucus membranes that line the nasal passages help collect and retain scent molecules. The shape of the nose can also influence how a dog perceives scents. Dogs are also wired to possess outstanding olfactory ability. Over a third of their brain is responsible for processing and decoding smells. They also have the “Jacobson’s Organ” that is located on the roof of the mouth, that functions to receive and decipher odorless pheromones.

Dogs use their olfactory sense to explore and learn more about their surroundings. They are also able to gather and retain sensory memories of places that they have been to with the aid of their sense of smell. It is also information gathered from their olfactory sense that helps stray dogs find their way home.
