You’ve heard the old saying that if a dog’s nose is wet it means they’re healthy. This is true, but why?
The noses of dogs secrete mucus. There are special glands on the inside of the dog’s nose that produce this. That layer of mucus sticks to the nostrils amping up the scent chemicals which improve the dog’s smell. That’s why they are do great at sniffing out things when being a search dog.
