Recognizing when a dog cough means serious cardiac concern.

A dog’s cough can be easy to overlook, often dismissed as a passing irritation or a mild case of kennel cough. Yet sometimes that subtle sound carries a warning about the heart. When fluid starts backing up in the lungs or pressure builds from a weakened heart, coughing can be one of the first outward clues. The challenge lies in telling a harmless cough from a life-threatening one. Understanding what makes a “heart cough” different helps owners act fast—protecting not only their dog’s comfort but also their life expectancy.
