Of the breeds listed above, Golden Retrievers, in particular, have a high risk of developing hemangiosarcoma in the United States. According to the Golden Retriever Club of America, Goldens have a lifetime risk of 20% for developing this disease.
Understanding which breeds are at risk may play a role in how actively you and your veterinarian screen for hemangiosarcoma. For example, pet owners of one of the above breeds may want to discuss more thorough checkups with their veterinarian once their dog reaches a certain age (e.g. 4 or 5), which may include ultrasounds or echocardiograms.
As we continue to review research about hemangiosarcoma, we may update this page with additional breeds. Remember, always consult a licensed veterinarian when making decisions about screenings, treatments, and other procedures.
