Why do dogs have wet noses?
July 29, 2012 9:04PM
Dogs' noses secrete a small amount of mucus which serves two purposes: to help their sense of smell, and to keep themselves cool. The thin layer of mucus 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' bodies release heat.
A dry nose CAN mean the dog is sick, but a perfectly healthy dog may have a dry nose, as well.
