Thanks, sounds like your little girl is doing something similar to my little guy. We were at the vet a few weeks ago and I did mention it (didn't go into much detail) and the vet just said toy dogs tend to have weak tracheas and didn't seem too concerned. I have to fight the urge to take the dogs to the vet's everytime they're even slightly out of the ordinary, so I do research online as much as possible. The closest thing I could find was collapsed trachea, but again, the symptoms don't quite fit. I hope you keep reading this thread for help with your little girl
