Tux reverse sneezes every once in awhile, I don’t really worry about it though. I’m not sure what the vet could do about it. I read something about how if you place your hand over their nose (or something like that), it will make them stop. Not 100% sure on the specifics of that though. I don’t really think it is harmful for them to do this, I wouldn’t worry unless he is doing it nonstop or something.
