What is a Heart Murmurs in Dogs?

A heart murmur is an abnormal sound heard during the heartbeat cycle, typically using a stethoscope. It often sounds like a whooshing or swishing noise, indicating turbulent blood flow within the heart. This condition can be caused by various factors and can affect dogs of any age, breed, or size.

Types of Heart Murmurs in Dogs

Heart murmurs in dogs are classified based on their timing, intensity, and location within the heart cycle. Understanding these classifications helps veterinarians determine the underlying cause and appropriate treatment.

Timing: Heart murmurs in dogs can be systolic, diastolic, or continuous, depending on when they occur during the heart’s pumping cycle.
Intensity: Heart Murmurs in dogs are graded on a scale of 1 to 6, with 1 being very faint and 6 being very loud.
Location: The specific location of the heart murmur in dogs within the heart can provide clues about its cause.

Causes of Heart Murmurs in Dogs

Heart murmurs in dogs can be caused by various conditions, ranging from benign to serious. Some common causes include:

Congenital Defects: These are structural abnormalities present at birth, such as aortic stenosis or patent ductus arteriosus.
Acquired Heart Disease: Conditions that develop over time, such as mitral valve disease or dilated cardiomyopathy.
Infections: Bacterial endocarditis or other infections can cause heart murmurs in dogs.
Anemia: Severe anemia can lead to turbulent blood flow and cause a murmur.
Age-related Changes: Older dogs may develop heart murmurs due to changes in their heart structure or function.

Diagnosing Heart Murmurs in dogs

Diagnosing a heart murmurs in dogs involves a combination of physical examinations and diagnostic tests. Here’s what to expect during the diagnostic process:
