Parainfluenza and Bordetella most commonly appear together in infectious tracheobronchitis, creating a disease that normally last from 14-20 days. The most common symptom is a dry hacking cough sometimes followed by retching. Many owners describe the cough as having a honking sound . A watery nasal discharge may also be present. With mild cases, dogs continue to eat and be alert and active.
Many times there is a recent history of boarding or coming in contact with other dogs.
In more severe case the symptoms may progress and include lethargy, fever, inappetence, pneumonia and in very severe cases even death. The majority of severe cases occur in immunocompromised animals, or young unvaccinated puppies. Diagnosis Diagnosis is usually based on the symptoms and a history of recent exposure to other dogs. Bacterial cultures , viral isolation, and blood work can be performed to verify individual agents of the disease but due to the characteristic nature of the symptoms are not routinely performed. There are two treatment options depending on the severity of the disease.
