I got a puppy Thursday and last night and this morning I noticed that he is sneezing ( I think ) it sounds like a sneeze or like something is tickling his nose and I am worried. Should I be? No discharge or cough, just sneezing. It has rained a bit here for the last few days and when he goes out to go potty his paws get wet, I dry him off. Do you think maybe he has a cold?
