I had a yorkie that got a blade of grass stuck in his nostril... I had to take him to the vet and he had to sedate him and flush it out... Blades of grass are very difficult to remove..
anyway, I had another yorkie that sneezed like you described and the blade of grass started showing and I pulled it out... she was ok after that..
It sounds like she has something up there..
I would take her to the vet tomorrow if she can wait that long and let them check her out.. If there is something stuck in there it could cause a nose bleed and possible infection...
Keep us posted.. Hope you figure this out.
