Quick Question #2: Why do dogs have wet noses?
There are two reasons why a dog's nose is always wet.
- To help their sense of smell.
- To regulate their temperature and keep themselves cool.
Their noses secretes mucus which helps with the absorption of scent chemicals from the air. In addition, the nose, along with the mouth and the pads of the feet, is one of the locations where dogs release body heat.
A dry nose can mean the dog is sick, but a perfectly healthy dog may have a dry nose, as well.
