Chapter 12 Canine Infectious Tracheobronchitis (Kennel Cough)
Canine infectious tracheobronchitis (ITB), also known as kennel cough, is a collection of highly contagious infectious diseases of the canine respiratory tract that cause acute tracheobronchitis and sudden onset of a paroxysmal cough lasting several days.
Consider ITB based on exposure history and clinical signs, especially the sudden onset of a severe cough in a previously healthy dog. A recent history of exposure to other dogs, especially under kennel conditions, is typical but not found in all cases. Hematology, radiography, airway cytology, and culture are not indicated unless ITB is severe with fever and bronchopneumonia. In typical uncomplicated ITB, these diagnostics are unremarkable or reveal nonspecific findings.
