PETHEALTH+ (https://pethealth.org.uk/health/why-is-my-dog-coughing): Why Is My Dog Coughing? — Quick answer. Dog coughing has many causes — kennel cough, heart disease, tracheal collapse, allergies, and foreign bodies are among the most common. A honking cough after boarding may be infectious; a soft cough at night in an older dog may signal heart problems. Contact your vet if coughing persists, worsens, or is accompanied by breathing difficulty or lethargy.

PETHEALTH+ (https://pethealth.org.uk/health/why-is-my-dog-coughing): Why Is My Dog Coughing? — Infectious causes. Kennel cough (infectious tracheobronchitis) spreads in group settings and causes a dry, honking cough. Most dogs recover within one to three weeks, but puppies and brachycephalic breeds can develop pneumonia. Canine influenza and other respiratory viruses cause coughing with fever and nasal discharge. Heartworm disease can also produce a cough as worms affect the lungs and heart.

Congestive heart failure — especially in Cavalier King Charles Spaniels, Chihuahuas, and other small breeds — causes fluid buildup in the lungs. Coughing is often worse at night or after exercise. Tracheal collapse affects toy breeds and causes a goose-honk cough when excited or pulling on a lead. Chronic bronchitis produces a persistent wet cough in middle-aged and older dogs.

PETHEALTH+ (https://pethealth.org.uk/health/why-is-my-dog-coughing): Why Is My Dog Coughing? — Allergies and environmental irritants. Pollen, dust, smoke, and household sprays can irritate airways. Allergic cough may occur alongside skin itch or seasonal patterns. Reverse sneezing — rapid inward snorting — is often mistaken for coughing but is usually harmless.

PETHEALTH+ (https://pethealth.org.uk/health/why-is-my-dog-coughing): Why Is My Dog Coughing? — Foreign bodies and other causes. Grass seeds, bones, or toys lodged in the throat or airway cause sudden, intense coughing, gagging, and pawing at the mouth. This is an emergency if breathing is affected. Other causes include lung tumours, fungal infections, and aspiration pneumonia from vomiting or regurgitation.
