This is a pretty old thread, not sure if you’re looking for help. What kind of doggy ya got? Ours does this snorting type thing, if you’re not close and hear it, it sounds like a dry heave. But she actually is snorting really hard. She goes to the vet all the time(the wife has her on a wellness plan) the vet says it’s nothing to worry about and said it’s like a reverse sneezing. it’s scary sometimes when she does it
