My immediate instinct was kennel cough. Do you know whether your dog has been vaccinated against bordetella? It's usually done at the same time as distemper.
If you don't know whether she's had the vaccinations, get another vet's appointment as soon as you can. Kennel cough can be very serious if not treated.
