How is she?
I haven't read all the posts yet….if she has been given the vaccine and her health isn't improving I would strongly recommend Amazon.com : Parvaid - All-Natural Parvo Aid for Dogs (1oz) : Pet Herbal Supplements : Pet Supplies
If you haven't already, STOP giving her the cheese etc and only give her boiled chicken & WHITE rice (until she stops the runs), along with the above I sure she will recover I 'm sure. Personally I would take her home especially if you have someone to care for her at home, maybe try and have your other dog at a friends, it is amazing what a relaxing environment can do for the illness and the dog. I would get a syringe and drip water into her mouth every so often.
All the best.
