Dogs cough with heart disease because a weakened heart causes fluid to back up into the lungs (pulmonary edema) or the enlarged heart irritates the windpipe, leading to a persistent, often dry cough, especially when lying down or after activity, signaling congestive heart failure (CHF) that needs urgent vet attention. This fluid buildup or pressure makes it hard for the lungs to absorb oxygen, causing breathing difficulties alongside the cough.
