Well, I just got done talking to the dog's owner. She finally called the Vet. (I think because I kept calling her and asking if she did yet!)
The Vet said that since she is getting better and the coughing is much better just to keep an eye on her. She said to keep her away from other dogs for at least another week to 10 days just to be sure.

I sure feel better now I am so glad she called and she is probably glad that I have stopped bugging her. Anyway, at least we all know that things are looking up!

Thanks for letting me vent!!
