Scientists from universities in Sweden and Hungary have posited thatdogs' noses are constantly cold because they act as "ultra-sensitive heatdetectors". Canines can sense the temperature of something before theytouch it. They added that dogs use their noses todetect tiny changes in temperature, such as when possible predators or prey arenearby. Humans generally only know something is hot after touching it, oftenwith painful consequences. It was common belief that the only reason dogs'noses are cold is to control and regulate their own body temperature. The researchers conducted experiments onsixteen dogs that had to detect the temperature of different objects in a room.The objects had different temperatures that humans could only differentiate bytouching them. The scientists said that the brain activity in the dogs showedthat they could discern which objects were warmer than others.
