Canine infectious tracheobronchitis (kennel cough) is one of the most prevalent infectious diseases in dogs.

Kennel cough is a fairly common ailment in dogs. People tend to associate it with dogs who either are being or recently have been boarded (or "kenneled"). But your dog need not be boarded to catch kennel cough. Kennel cough is caused by an airborne virus, which is highly contageous.
