I am no expert and am only just learning to deal with Collapse Trachea with Moe, but from my limited understanding of this situation, the weak tracheal "membrane" and what I call support rings, cause Im no expert, are already there, there are what our vet calls triggers, that sets the collapse trachea, Honking and such off, so it may be possible, that the vomiting was violent enough to the trachea, as you have trouble breathing when you vomit, to have "triggered" the response of the collapsed trachea, so not the actual cause of the situation as in making him have collapsed trachea, but more the catalyst that set it off.For Moe it can be something so simple as my hairspray, which now I have to use away from him, as it triggers his problem.Be sure to find out from your vet what level of Collapsed trachea your baby has, as there are varying degrees of it and it was a great comfort to me to see Moe only has the mild version of it.
