Currently, there are no scientifically confirmed reasons for wet noses in dogs. But we are sure that the reasons we are about to list will be true in most cases. Let's start.

1. They lick them a lot

All dogs will lick, and some will have a habit of licking their noses. There could be a variety of reason why your dog does it, but the most common ones are because their nose is dirty and they want to clean it – if your dog loves to dig and stick his nose in the dirt, he will probably lick his nose to clean it up.

The dog will sniff the environment to gather all sorts of scents to get information. By licking their noses, dogs will be able to test the environment. Their taste glands can give them more information about a specific thing.

2. To cool themselves down

You probably already know that dogs cannot cool themself like humans with sweat glands. To cool themself down, they will pant. But did you know that dogs have a small number of sweat glands in their snout and paws? Small amounts of sweat will come through their nose when they want to cool themselves down, which will help control their body temperature.

3. Picking up scents

Wet nose will help your dog catch a better smell from the environment. This will help the dog gather chemicals that can give them better information about specific things. With this, they can easier follow a specific scent they find interesting.
