A PubMed-indexed article titled “The Approach to Chronic Cough in Dogs and Cats” outlines a comprehensive approach to diagnosing and managing chronic cough in companion animals.
Three quick summaries of the same article, tailored for different readers.
For owners, chronic cough is frustrating because many problems can sound similar from across the room. A dog may cough from airway inflammation, heart enlargement, tracheal collapse, infection, parasites, or irritants. Cats may show cough, wheeze, or breathing changes that need a different frame. The useful home step is to note duration, triggers, breathing effort, exercise tolerance, appetite, and video if safe.
Good source for why cough workups can take several steps.For vet techs, chronic cough cases improve when intake captures onset, duration, frequency, sound, triggers, exercise tolerance, respiratory rate, syncope, gagging, vomiting-like episodes, travel, parasite prevention, environmental smoke or aerosols, and prior medications. That history helps the veterinarian separate upper airway, lower airway, cardiac, infectious, and irritant possibilities. A good cough video can be surprisingly useful when the patient will not cough in the clinic.
Useful for building a cough-history checklist.For pre-vet readers, chronic cough is an excellent diagnostic reasoning exercise. The first step is localization: upper airway, lower airway, pulmonary parenchyma, pleural space, or cardiac-associated cough. Then the timeline, signalment, auscultation, imaging, and response to therapy refine the differential. The trap is jumping straight from “cough” to one favorite diagnosis without asking where the cough is coming from.
