I found this on another thread here:
"Collapsed Trachea is different than reverse sneezing. Reverse sneezing is when the back of the throat spasms. The dog stands still, stretches out their neck, and often becomes bowlegged while they are trying to get air. It honks, wheezes, and often snorts during reverse sneezing episodes. Often the spasms will cease if they swallow a couple of times or if you close off their nostrils so it has to breathe through its mouth for a few seconds."
Don't know if that helps.
