Section: Overview
Coughing is a common protective reflex that clears secretions or foreign matter from the throat (pharynx), voice box (larynx), windpipe (trachea) or airways, and protects the lungs against aspiration. It affects the respiratory system by hindering the ability to breathe properly. Common causes include obstruction in the windpipe, bronchitis, pneumonia, heartworm disease, lung tumors, kennel cough and heart failure.What to Watch For Watch for a chronic cough, or one that lasts for more than two or three weeks. It can begin suddenly or develop gradually. An occasional, infrequent cough is normal. See your veterinarian if your pet has a chronic cough.DiagnosisVeterinary care should include diagnostic tests to determine the underlying cause of the cough.
