Filaroides Hirthi Lung Worms in Dogs
Questions were whether it was highly infectious – (and it is, the larva are infectious when passed in the animals’ poops and discharges) AND they can harbor the parasite and it can get worse on its own, with passage from lung to bowel and back again making it worse and worse WITHOUT any environmental exposure to more infectious poop.
Also, does Heartgard Heartworm Preventative actually prevent the progression of the infection in dogs? I don’t have nor have I found a clear answer on that.
