Hi Lynn,
That sure sounds infectious, doesn't it? Reverse sneezing connotes gasping, spasmodically, like the airways have temporarily closed. Could last 10" which seems like an eternity to a worried dog mom. I liken it to a sudden asthma attack, though it's not, strictly speaking.
This flu is characterized by a harsh dry cough that often comes in a bout of several coughs, and ends in a gagging retch. Most, but not all, started with full on sneezing, according to reports I've gathered.
So, I'd guess you had something different, unless you saw some of those symptoms in each sick dog.
