Heartworm disease is a catastrophic, progressive condition caused by foot-long worms that inhabit the heart, lungs, and associated blood vessels. Because the disease is transmitted exclusively by mosquitoes, the risk is virtually ubiquitous. Once infected, dogs face grueling, expensive, and risky treatment, while there is currently no approved medical treatment for heartworms in cats.
The Silent Progression
In its early stages, heartworm disease presents no visible symptoms. By the time a pet exhibits clinical signs—such as a persistent cough, severe fatigue, or a swollen abdomen—the disease has reached an advanced, life-threatening stage, causing irreversible damage to the cardiopulmonary system.
The Golden Rule of Prevention
Prevention is incredibly simple and highly effective compared to treatment. Administering a monthly oral or topical preventative, or an annual veterinary injection, eliminates microscopic larvae before they can mature. However, annual blood testing is strictly required before starting or refilling preventatives to ensure the pet hasn't already contracted the disease.
