Heart Health and Cardiovascular Care for Your Afghan Hound

Quick answer

Afghan Hounds are known for their elegance and speed, but they also have specific health considerations regarding their heart health. While these conditions are not guaranteed to occur, they are recognised tendencies within the breed. By learning to monitor your dog's resting breathing rate, gum color, and general energy levels, you can catch subtle changes early. If you notice persistent lethargy, fainting, or difficulty breathing, seek a veterinary evaluation immediately to determine if further testing is required.

Cardiac Hemangiosarcoma

Cardiac hemangiosarcoma is a recognised tendency in the breed. This condition involves the development of tumors that affect the heart or the vessels surrounding it. Because the heart is a vital organ, any growth here can interfere with its ability to pump blood effectively throughout the body.

At home, you might first notice that your dog is less interested in their usual walks or seems to tire much faster than normal. You may also observe episodes of weakness or sudden collapse, which occur when the heart struggles to maintain blood pressure. In some cases, the first sign might be a pale or white appearance of the gums, indicating poor circulation.

When you visit the vet, they will perform a physical examination to listen for abnormal heart sounds or muffled heartbeats. If they suspect a problem, they will likely use imaging tools like an echocardiogram or thoracic radiographs to view the structure of the heart and look for masses. The urgency of this condition is high, as it can lead to sudden internal bleeding. If your dog collapses or experiences severe difficulty breathing, this is a medical emergency that requires immediate intervention.

Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is another recognised tendency in the breed. This condition causes the heart muscle to become thin and weak, which prevents the heart from contracting with the necessary force to circulate blood. Over time, the heart chambers may enlarge, leading to congestive heart failure.

As an owner, you should watch for a gradual decline in stamina. Your dog might pant more than usual, even when resting, or seem restless at night because they cannot get comfortable. A cough that develops after exercise or when lying down is also a common observation. Because this condition progresses slowly, it is easy to mistake early signs for simple aging or fatigue.

Your vet will use a stethoscope to listen for murmurs or irregular rhythms, which are often the first clues. An echocardiogram is the gold standard test to confirm the diagnosis, as it allows the vet to measure the thickness of the heart walls and the efficiency of the heart's pumping action. While the exact way this condition passes down is not settled, regular screening is the best way to manage the risk. If you notice your dog struggling to breathe or showing signs of fluid buildup in the abdomen, take them to the vet promptly.
