Infectious Canine Tracheobronchitis (kennel cough) is a contagious respiratory infection in dogs caused by viruses, bacteria (Bordetella) and Mycoplasma. Although uncommonly contagious to people, those who are immunosuppressed are most susceptible. Infectious canine Tracheobronchitis is most severe in puppies 6 weeks to 6 months of age. Dogs will usually exhibit a dry hacking cough followed by a gagging or spit up of mucus. Excitement, or exercise, can exacerbate the cough. The time of exposure to manifestation of symptoms is 4 days. In most pets the cough is mild with no change in behavior or appetite, because the lungs are not infected. Rarely pets can have appetite loss, lethargy, and difficultly breathing. The diagnosis is made by eliminating other causes such as lung infections, foreign bodies in the throat or airway and canine influenza. Blood tests and x-rays may be indicated. Antibiotics and cough suppressants may be indicated depending on the natures of lung involvement. Isolate infected dogs. An intranasal vaccination every 6 months will most often prevent severe illness from affecting your pet.
