Why do dogs have cold noses? - Live Science

Why do dogs' noses usually feel cold and wet.

But so is a warm nose, especially after snoozing, said Anna Bálint, a researcher who studies animal behavior at Eötvös Loránd University in Budapest, Hungary.

But why are dogs' noses cold, and could there be a benefit? .

One idea is that the dog's cold nose could help the furry beast regulate its body temperature.

But the nose tip is so small, it's likely unable to meaningfully contribute to a dog's overall thermal regulation, Bálint said.

By the time Bálint joined the project, the team had already learned that the nose tips, or rhinariums, of dogs and carnivorous animals are usually cooler than those of herbivores.

The specific region that lit up in the dogs — known as the somatosensory association cortex — helps bring together different sensations such as vision, body position and warmth, she added.

Given that this left-sided neural region lit up when the nose tip was exposed to a warm surface, it's possible that dogs, and possibly other cold-nosed animals, could be using a heat detection sense along with other senses in their 'hunting toolbox' when they're in pursuit of prey, the researchers said. .

Although the recent study, published in February 2020 in the journal Scientific Reports, is too small to firmly close the case on cold noses, Bálint said a cold nose could be more sensitive to differences in temperature.

So, why is a dog's nose cold.
