reverse sneezing? collapsed tracchea? or he could just snort!
My mom has a shih tzu who has snorting sessions like that but I guess its common in snub nosed dogs... yorkies are not snub nosed though. If you are a little concerned give your vet a call and ask. My dogs snort a LOT.. but they do not sound in distress, almost like they are sneezing and snorting at each other when they play or want my attention.
