Kennel cough
Antibiotics are given to treat any bacterial infection present.  Cough suppressants are used if the cough is not productive (nothing is being coughed up).  The usual outcome is good.  Prevention is by vaccinating for canine adenovirus, distemper, parainfluenza, and Bordetella.  In kennels, the best prevention is to keep all the cages clean.  Most kennels will not board dogs without proof of vaccination.
