A cold, wet nose is one sign of good health in dogs and cats. However, even a healthy pet can have a warm, dry nose on occasion. On the other hand, really sick pets can also have cold, wet noses.
What does all this mean?
Simply that any one indicator of health is not 100 percent accurate all the time. Sick pets with cold noses should be seen by your veterinarian. And by the same token, pets with warm, dry noses that are showing other symptoms such as lethargy or not eating should also be seen by a doctor.
