I took Lola in scared that she had a collapsed trachea because she always made a backwards sneezing sound....and I then learned about the reverse sneezing from my vet. My vet said that a collapsed trachea sounds like goose honking. Lola reverse sneezes a lot and it sounds like a sneeze more so than a honking. Your little baby sounds like she is making more of a goose honking to me than Lola's sneezing noise. Only a vet would be able to tell you for sure though
Keep us posted!
