Scientists found why dogs' noses are so cold

Scientists believe they have solved the mystery surrounding the low temperature of dogs' noses, Sky News reports.
According to a study, this phenomenon is due to their noses being fitted with extremely sensitive heat receptors — and this has nothing to do with regulating their body temperature, as previously thought, transmits “Focus.”

Scientists from Sweden and Hungary discovered that when the air temperature is 30 degrees Celsius, the canine rhinarium — the tip of its snout — is always five degrees colder.

And when the temperature outside is zero degrees, the canine is about eight degrees Celsius. These factors are leveled pro about 15 degrees.

This led scientists to believe the tip of the canine nose served as a receptor, according to the study published in Scientific Reports. It also says that with this recipe, the canine nose can spot very weak heat sources — such as small animals — at about a distance of up to a metre and a half. This was confirmed by an experiment with real animals.
