healthypets.mercola.com/sites/healthypets/archive/2020/07/02/dog-nose-can-detect-heat.aspx Story at-a-glance New research suggests dogs use their noses to detect “weak thermal radiation,” aka body heat emanating from its would-be prey The rhinarium — the naked and often moist skin on the tip of a dog’s nose — is both prominent and richly innervated, meaning it’s well supplied with nerves, suggesting it has a sensory function Dogs’ nose-tips are considerably colder than the rhinaria of many herbivorous animals, which led the researchers to suspect that they may be particularly sensitive to radiating heat Three pet dogs correctly detected an object with the weak thermal radiation in an experiment When exposed to an object emitting weak thermal radiation, the left somatosensory cortex was more active in the dogs’ brains; this area plays a role in co-registering different sensory information Dogs may now join other creatures known to sense weak thermal radiation, which include certain insects, snakes and vampire bats My notes: Very informative!
