An unusual case of Angiostrongylus vasorum infestation occurred in a three‐year‐old female cavalier King Charles spaniel. The dog presented with signs consistent with right otitis interna, followed by the appearance of a free‐swimming nematode in the anterior chamber of the right eye. The dog died of acute heart failure before surgical removal of the parasite was possible. Post mortem examination confirmed the presence of large numbers of worms in the pulmonary artery and right ventricle. These worms were identified histologically as A vasorum.
