The Bordatella vaccine is what we call "modified live" . This means that the actual virus is altered slightly to make it non-infectious, but still recognizable and stimulating to the immune system. If your dog is coughing, my suspicion is she contracted it based on exposure pre-vaccine. Generally this virus will run its' course within a month, but antibiotics can help prevent any secondary bacterial infections. A cough suppressant can also help keep her more comfortable.
