Why Is My Dogs' Nose Wet?


Enhance Their Ability To Smell - A dog sees the world through its nose, which is why they have they can smell up to 10,000 times better than humans. A dog is said to have up to 300 million nose receptors, compared to our 6 million!

The nose secretes mucous, and the thin layer of mucous keeps the nose wet and the canals moist. A damp nose works a lot better than a dry one as the scent particles can stick to it. This enables a dog to understand each smell. 
Licking - We always see our dogs licking their noses; this not only keeps them clean but also helps with scent detection. They absorb the mucus, which is covered with scent particles into their mouth and to an olfactory gland, Jacobson's organ, which is located in the nasal cavity and opening into the top of the mouth. 

Jacobson's organ helps them to understand the smells further. The primary function of this organ is to coordinate basic functioning, e.g., to be able to detect a mate and find its way home. Search and rescue dogs supposedly extend their scent capability by licking the air.
Cool Down - Dogs are unable to sweat through their skin, like humans. They cool down by panting and by secreting through their nose and paw pads. This helps keep them cool and control their temperature. So their cold wet nose may be them trying to cool off.

Woken From A Nap - While they sleep, dogs do not lick their noses. Therefore they can dry out.
