Heart worm Circulating infection process
Pet After a bite from an infected mosquito, heartworm larvae migrate through the tissue. After three months, they enter the bloodstream and end up in the pulmonary artery. Left untreated, larvae can grow into adult worms in just over 6 months—leading to heart, lung, liver and kidney damage.
But with HEARTGARD Plus or OTHERE, you can kill the heartworm larvae that are transmitted to your dog by those annoying bloodsuckers, preventing heartworm disease.
