Ok, so what constitutes "happy to see you" sneezing" versus sick sneezing? Buddy has had a bit of a random sneeze since I got him but I think it's getting more frequent (esp. when he wakes up). There is some clear nasal discharge. The vet told me to bring him back if I heard and congestion but I am not sure what that exactly constitutes (he is not coughing). Anyone else have this problem? Suggestions?
