More than a million pets in the United States have heartworms. Let that sink in, because it is one of the most horrible statistics regarding our furry friends. Heartworm affects an animal’s health and quality of life long after the heartworms are gone. These creatures are heartless in what they do. The American Heartworm Society (https://www.heartwormsociety.org) reports that, typically, most pet owners would not knowingly put their pet at risk to become infected with the deadly disease, but millions of these same owners fail to protect their pet from the infestation. For a disease that is easily prevented, there are no excuses.
