Reverse sneezes?

Lucy will do that thing where she snorts, and sucks air in. I've always said her sneezer is stuck. I'm hoping you all know what I mean.
Anywho, for the last four nights she's done it consistently. It used to be a rare thing. Every night now, and it lasts a long time. Ethann said he's going to video her tomorrow, then we'll have length of time, and maybe I'll be able to post it. Does this happen as pugs get older? Is is cause Lucy is a bit of a train wreck? Any thoughts?

ETA: Ignore me, I should search before I post. Mel, that article is great!

Spring allergies?

Maybe her palette or throat is a little swollen at the moment - allergies or even a cold?

I was thinking allergies too.
