My dog's nose is dry, Is he sick?

A dog's nose is usually cool and moist. It can be black, pink, or self-colored (the same color as the coat), depending on the breed. Nasal discharge should be clear, never yellowish, thick, bubbly, or foul smelling. A cool, wet nose does not necessarily mean the dog is healthy, and a dry, warm nose doesn't necessarily mean he's sick. Taking his temperature is a better indication of illness.
