This report details the post-mortem discovery of a larva of Spirocerca lupi in the caudal thoracic aorta of a 2-year, male bush dog (Speothos venaticus). This individual presented no clinical symptoms of the parasite's presence prior to its sudden death. The cause of death was determined to be acute bleeding following the rupture of an aneurysm in the caudal thoracic aorta as a result of the parasite located there. This is the first report of S. lupi in a bush dog.
