lungworm, any of the parasitic worms of the superfamily Metastrongyloidea (phylum Nematoda) that infest the lungs and air passages of mammals, including dolphins and whales.
Examples include those of the genus Metastrongylus that live in pigs and those of the genus Dictyocaulus that live in sheep and cattle.
Rat lungworm, or Angiostrongylus cantonensis, can be transmitted between mollusks -- like snails and slugs -- and rats, and it can make humans sick.
According to the Hawaii state Department of Health, when infecting a human, the parasites can't reproduce or mature, and they will die in due course.
Different to intestinal worms, such as the tapeworm and roundworm, adult lungworm live in the heart and blood vessels of the lungs of dogs, which can be life threatening if left untreated.
Symptoms of lungworm in dogs include.
Coughing.
Changes in breathing or struggling to breathe.
Going off food.
Upset stomach with vomiting and/or diarrhea.
Loss of weight.
Tiredness and depression.
Unexplained or excessive bruising.
Pale gums.
