Hi there I am sorry to hear your Gorgio is having health issues. Here is a great link for videos on Kennel cough, reverse sneezing, collapsed trachea. I think Giorgio may have been reverse sneezing my Buster does it a lot. When he is having an episode I softly stroke his neck to try and calm the spasms or I hold a finger over his nose to block the air cycle so he breaths just through his mouth. It is like breathing hiccups where the air is going in reverse direction through the nose and out the mouth I think. A good place to ask these questions are in the sick forum as many helpful people check the threads there and can offer advice. Best wishes to you and Giorgio and I hope your baby is feeling better soon.
