What Does the Heart Do?                        

The heart, blood and blood vessels make up the system that supplies the body's tissues and organs with oxygen and nutrients.

Oxygen-depleted blood comes from all parts of the body to the chambers on the right side of the heart. The blood is then pumped through the lungs, where oxygen is added to it.

Oxygen-rich blood returns from the lungs to the left side of the heart and is pumped out, delivering oxygen to all the body's tissues.

 

Types of Heart Disease

There are two types of heart disease, congenital and acquired. Congenital heart disease is present at birth and is rare. Acquired heart disease develops over time, usually beginning during middle-age and affective many older dogs.

The most prevalent type of acquired heart disease, Chronic Valvular Disease (CVD), is also known as mitral regurgitation, mitral valve disease and valvular insufficiency, among other names. In CVD, the heart valves gradually lose the ability to close effectively, which causes abnormalities in blood flow.

The second most common kind of acquired canine heart disease, Dilated Cardiomyopathy (DCM), caused the muscular walls, of the heart to become thin and weak, and the chambers to dilate.

Both CVD and DCM result in the same serious condition which is called heart failure.

 

SAS (Subvalvular Aortic Stenosis) is the most common and widespread form of heart disease within the entire Golden Retriever species. Before you breed your Golden Retriever, you should always have him examined for heart disease by a certified veterinary cardiologist. If the cardiologist detects a heart murmur, he will recommend additional tests for your dog.

In the event that the results prove negative, it doesn't necessarily rule heart disease out, as some milder forms may still be present, although undetectable.

 

The signs of heart failure include the following but not limited to only these

Although the signs of heart disease may appear mild at first, and may be mistaken for signs of aging, heart failure is a serious, progressive problem and can be life-threatening. Not all signs may be present at the same time. Some signs may also be cause by other serious conditions

 

If a Golden Retriever is diagnosed to have any type of heart disease, he should not breed.

Breeding Golden Retrievers who have heart disease can lead to serious and sometimes fatal results.

To be on the safe side, you should always have your Golden tested for this disease before you plan on breeding.
