Heartworm disease is a serious illness that can rob your dog of its health and even its life.
Heartworm larvae are transmitted by infected mosquitoes that bite the dog and deposit heartworm larvae on the dog's skin. The larvae migrate through the tissue and into the bloodstream of the dog where they continue developing. By the time clinical signs of heartworm disease appear, the disease can already be in its advanced stages.
Heartworms spend their adult lives in the right side of the heart and the large blood vessels that connect the heart to the lungs. The adult worms block the heart and major blood vessels leading from the heart to the lungs, liver, and kidneys and can grow up to 12 inches long.
Heartworm disease has been reported in all 50 U.S. states. HEARTGARD® Plus (ivermectin/pyrantel) can help prevent heartworm disease.
IMPORTANT RISK INFORMATION: HEARTGARD is well tolerated. All dogs should be tested for heartworm infection before starting a preventive program. Following the use of HEARTGARD, digestive and neurological side effects have rarely been reported.
