Reminds me of when our Norton had the same thing. We fed him baby chicken food, because it smells....I had a vaporizer going near to him to help with the congestion. I also mix up some liquid gold seal for nose drops and that helped to open him up. If you do not have gold seal, try LITTLE NOSES,, it is sold at the grocery store...Will light a candle for Kiri!! Feel better soon....Sandra
