Does the Heart Do?
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

present at birth and is rare. Acquired heart disease develops over time, usually
beginning during middle-age and affective many older dogs.
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.

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

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

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