Bronchopulmonary Disease

Chapter 162 Bronchopulmonary Disease

Diseases of the tracheobronchial tree and pulmonary parenchyma are very common in canine and feline patients and are responsible for substantial morbidity in the pet animal population. Determining the underlying disease responsible requires an understanding of clinical signs, interpretation of laboratory and radiographic findings, and collection and analysis of airway samples. Individualized therapy will be most likely to lead to amelioration of signs. Many respiratory tract diseases are chronic in nature, and the goals of therapy become controlling clinical signs and avoiding progression of disease.


Coughing, respiratory distress, abnormal breathing, and exercise intolerance are the presenting complaints most commonly observed in cats and dogs with diseases involving the respiratory tract.

Overview in Dogs

A wide variety of infectious, inflammatory, degenerative, and neoplastic diseases cause clinical signs referable to the respiratory tract in dogs.

Overview in Cats

Cats may present with a history of acute or chronic respiratory disease. Cats with chronic respiratory disease may present emergently with acute signs of respiratory discomfort because stress can lead to rapid physical decompensation.



Clinical Signs


The presence of a honking cough in a small-breed dog is often considered diagnostic of tracheal collapse. Consider a full diagnostic workup in order to identify and treat all coincident disorders that complicate the clinical presentation.



Clinical Signs

Physical Examination


The history of a long-term cough in an otherwise bright and healthy dog is suggestive of chronic bronchitis, which is largely a diagnosis of exclusion. Pneumonia and pulmonary neoplasia can cause similar signs. Also, dogs often have separate or concurrent cardiopulmonary conditions such as tracheal collapse, bronchial collapse, bronchial compression, or heart failure. A complete diagnostic workup assesses the role each condition might play in the generation of clinical signs and aids in developing a therapeutic plan. Laboratory evaluation (complete blood count [CBC], chemistry panel, urinalysis) should be done to evaluate systemic health, although there are no typical abnormalities for chronic bronchitis. The diagnosis is based on the history, clinical findings, chest radiographs, and airway sampling to rule out other pulmonary causes of cough.
