Understanding Heartworm Disease
Heartworm is a microscopic parasite that is transmitted into the body of an animal through the bite of a mosquito. The parasite cannot be transmitted from one animal to another or to humans. Once the microscopic worm is in the bloodstream, it travels to the heart and lungs where it begins to grow and multiply. Eventually, the number of worms begins to crowd the heart and lungs and noticeable symptoms appear, such as coughing, weakness, poor condition, and labored breathing. The best way to protect your pet against heartworms is to provide preventative medications that are available through your veterinarian.
