Ben's had a form of kennel cough even though he had the usual vaccinations and the 'squirty' one up the nose! He wasn't too bad though and it was more snorting and sneezing rather than coughing. The vet prescribed nothing the first time, but the second time he had an inflamed bowl/intestine as well so he had antibiotics - the kennel cough symptoms disappeared in two days or so. Not sure if the antibiotics work for kennel cough in general but they did for him.
