Why Is a Dog’s Nose Wet?
There are a number of reasons that have been proposed for why a dog’s nose is wet, and it may be that science doesn’t yet know the exact answer.
However, we do know there are glands inside a dog’s nose that secrete a thin, watery material that likely contributes to the moisture, much like the fluids found inside our own noses. This liquid wicks out to the nose surface, evaporates, and then helps to cool the dog.
The nose pad and the footpads are the only places dogs are able to sweat, so this cooling mechanism (along with panting) can be important to them, especially in hot weather. Additionally, our canine friends tend to lick their noses frequently, which—much like humans licking their lips—tends to keep their noses moist.
This moisture may also help humidify the air as it moves into a dog’s nasal cavity, which keeps it from drying out their respiratory tract and may even help prevent respiratory infections.
Some people speculate that the moisture helps dogs retain scents, thus improving their sense of smell.

Why Are Dogs’ Noses Wet?
The main reason dogs’ noses are wet is because they secrete a mucous that aids their sense of smell. While humans rely primarily on their vision to survive, smell is a dog’s strongest sense. Since scent particles stick to wet noses better than dry noses, a wet schnoz simply works better!
Dogs will also lick their noses to keep them clean, and the saliva causes them to stay damp. Additionally, they don’t have sweat glands in their skin, so dogs have a cooling mechanism in their nasal passage, and also sweat through their paws.
A dog’s environment can also add moisture to their nose. If they sniff damp grass or stick their nose in a puddle, their nose will stay extra wet.
