Lily does the reverse sneezing thing (gently stroking her throat stops it almost immediately) but she also does the hacking up the furball thing now and then. I really hate that one because I don't know how to stop it. I always think it's allergy related but I could be wrong. :?Alli said:I always thought the reverse sneezing thing was more of a honking intake of air sound that goes on for at least 10-30 seconds. The choking up a hairball thing is different...it's more like a cough, like he's trying to get something out. It's the second one your pup has? I have no idea what that is :? Wish I did!
