About ProHeart
ProHeart is an injection that prevents heartworm infestation in dogs, given either once a year or twice a year depending on the formulation, and it also treats existing larval and adult hookworm infections. Because a veterinarian administers it, it removes the monthly compliance problem that oral heartworm preventives depend on — a different approach to the same disease Simparica Trio covers in a chewable tablet.
