Dogs’ ability to detect scents is up to 10,000 times more sensitive than the human nose.. A wet nose enhances the ability to trap olfactory (connected with sense of smell) chemicals in the secretions produced in the glands of the nose.

Some dogs lick their nose, contributing to the “wet nose” look and enhancing the process of scent detection as those chemicals are processed in olfactory centers in the roof of their mouths. Dogs also produce more secretions from their nose as a way of regulating body temperature.

Sweat glands are found in the feet and nose and as such, a wet nose helps keep them cool.
