We just got back from the vet and no upper respitory infection. The vet thinks that it might be due to her throwing up yesterday and might of caused an irritation. Or it could be that she has something stuck in her nasal passage. I don't use down bc of my allergies.
They gave her a shot of an antiflammatory to reduce any swelling but if it isn't better in 2 days she has to go in and have her nasal passage flushed.

I can't imagine what got stuck unless when she threw up food went up her nose

She sounds awful poor baby
