I've had patients coming with wet noses showing 106oF temperature while some, having dry nose showing perfectly normal temperature, so what does it means  NOTHING! The state of the nose depends upon what a dog is doing or has recently been doing as well as the climate. Sleeping dogs generally have dry noses and while exercising, their noses are usually wet. Wet nose is useful because scent molecules are trapped in moisture, enhancing the animals scenting ability. If the pet has fever, you should rather rely on symptoms like lower levels of energy and appetite rather than the nose.
