This might be the new canine influenza or if the dog has had no shots you may be fighting distemper.
You can try using a sports bottle for fluids and using plain pedialyte will give her a little extra energy instead of plain water.
You can clean the nose with sterile saline like is used by contact lense wearers. You can bring her in a steamy bathroom to help with congestion.
She maybe trying to cope with pneumonia and for that you'd need antibiotics. The green color in the discharge indicates a bacterial infection.

Antibiotics may be your best help so another vet visit or at least a call is needed to get them.
