It is a myth that a cold wet nose is a sign of a healthy dog and a warm dry nose is a sign of illsens. If nothing else about your dog has changed (appetite, activity level, sneezing or coughing, colored discharge from nose or eyes) then there is nothing wrong with her. Her nose is just dry. Could be that she just woke up (both of my dogs' noses are warm and dry right after a nap) or she hasn't taken a drink very recently or it's dry in your house.
