Pulmonary Edema in Dogs
Pulmonary edema occurs when fluid accumulates in the tissues, airways, or air sacs of the lungs. The common term for this disorder is fluid in the lungs. It may occur alone, with circulatory disorders, or be caused by an allergic reaction, infectious disease, electric shock, or head injury.
There are four common heart conditions that can result in canine pulmonary edema including:
- Mitral Valve Disease – The valves that take blood to and from the heart fail to close properly, causing blood flow to slow and leak from the capillaries.
- Dilated Cardiomyopathy – The ventricular section of the heart becomes enlarged or dilated, affecting blood flow. This condition is prevalent in Doberman Pinschers, Irish Wolfhounds, great Danes, and boxers.
- Myocardial Disease – The heart enlarges and causes problems with blood flow.
- Pericardial Disease – Fluid builds up in the protective sac around the heart, constricting the heart and affecting blood flow.
It is important to determine the cause. If the condition is due to a heart disorder, then the heart condition needs treatment.
