<human>: Can you provide a brief rundown of the text in within 3 sentences?

We adopted an 8 year old Schnauzer two days ago. For the past eight years she has lived with an elderly woman, until very recently when the woman was placed in a nursing home and the dog in a foster home.  She appeared healthy when we spent time with her and adopted her. 
 
My concerns are as follows:

In the car she began sneezing thick green mucous with bloody streaks.  I took her to the vet on the foster agency list, but came away with little more than I would have learned online. (she has one blocked nostril and he doesn't know why)  I want to taker her to our vet, but I am waiting on the agency to get back with me and get me the rest of her records. 

I have paperwork that shows that she is up to date on her shots and heartworm prevention. She is also has a microchip.  She is very well housebroken, as sweet as can be, and we have really fallen for her. The vet said there should be some blood work or xrays, but the agency should provide it.

I am afraid to wait much longer. She doesn't eat well, but I really think that she is just very picky (we are pretty sure that she ate people food with the way she acts when we cook.) She is active and happy to have a home, but she snores in her sleep and snots on everything.  

Not knowing if it is an infection or endangering the other animals is nerve wracking..  

If it is serious I am also worried about care or the other animals. 

We don't have any other dogs, just a bunny and a bird, but not knowing what is causing her condition has me concerned for their health.
