The nose makes moisture
VCA describes glands that produce mucus and watery fluid in the nasal area. Moisture helps scent chemicals collect. This is a general explanation of the nose's function, not a way to decide whether a particular discharge is normal.
Dogs can lick the nose to clean it and move scent-containing material toward the mouth, as described by VCA. Seeing a lick does not identify a medical cause or mean you should repeatedly touch or inspect the nose.
A dog exploring damp grass or another wet surface may pick up moisture. Write the context if it is relevant, but do not assume a visible change is explained by that context. An observation about where the dog has been is different from a diagnosis.
A simple mechanism does not create a home test. We supply no nose-temperature cutoff, moisture scale, hydration verdict or treatment recommendation. If the nose has changed or you are worried, ask a veterinarian about the actual dog.
