Clearing the Air on Coughing and Heart Disease

Clearing the Air on Coughing and Heart Disease

Coughing in your pet is a red flag. If your pet has a heart murmur coughing is a sign you need to take your pet to your Veterinarian.

 

Why is my pet coughing if they have a heart problem?

When a dog is coughing due to heart disease, often it is the result of the blood from the left ventricle or chamber of the heart being pushed back into the atrium and that usually occurs due to some type of damage to the heart valves or some type of change in the valve.

Eventually the atrium or chamber of the heart starts getting bigger and swelling; when this happen it will push on some of the main airways in the lungs. This pressure will cause your pet to frequently cough and be short of breath.  At this time the blood will start moving more slowly through the lungs resulting in more fluid leaking out into the alveolar spaces of the lungs leading to fluid on the lungs which will make your pet cough.

This condition causes more than just coughing, it can cause difficulty breathing and increased respirations. You will notice this typically after exercise, excitement, or when the animal has first gotten up after sleeping.
