False

The common belief that a healthy dog has a cold, wet nose and a sick dog has a hot, dry nose is a wive’s tale. The moistness and temperatures of dogs’ noses fluctuate day to day, even hour to hour and are most likely related to environmental conditions or the dog’s recent activity. A dog can be perfectly healthy and have a warm, dry nose or a dog can be really sick and have a cold, moist nose. Better indicators of a dog’s health are symptoms such as not eating, not drinking, or behaving oddly.
