New research reveals that the naked, wet skin on the tip of a dog's nose works as an infrared sensor, allowing them to detect small changes in temperature, such as when other aninmals are nearby.

The study was undertaken by scientists at Sweden's Lund University and Hungary's Eotvos Lorand University.
Anna Balint, the lead author of the study, said this may result in revisiting questions about dogs' behaviour, and prey-predator interactions.
Balint also said future research might reveal the same sense in other carnivorous species.
