TheraHeart chewables are the easy, once-a-month way to protect your dog from heartworm disease, ascarids and hookworms.

TheraHeart chewables eliminate the tissue stage of heartworm larvae (Dirofilaria immitis) for a month (30 days) after infection and treat and control ascarids (Toxocara canis, Toxascaris leonina) and hookworms (Ancylostoma species, Uncinaria stenocephala).
