Plain-English summary
A 7-month-old male Pomeranian was brought in for severe breathing problems that had lasted for two weeks. Despite receiving supportive care, including oxygen therapy, the dog sadly passed away five days later. A necropsy revealed multiple nodules in the trachea caused by a lungworm infection from a parasite called Filaroides osleri. This infection led to significant damage in the dog's respiratory system, which ultimately contributed to its decline.

Abstract
A 7-month-old male Pomeranian had severe dyspnea for 2 weeks. The lateral bronchogram showed a stenosis of the trachea. Inspite of supportive therapy including supplemental oxygen, the dog died 5 days later. Six pedunculated nodules were recognized in the mucosal surface of the trachea at necropsy. The tracheal nodules were histopathologically granuloma characterized by many coiled parasites containing a little collagen fibers, lymphocytes, plasma cells and macrophages. Female parasites had a lot of embryonated eggs in the uterus. Immature worms were observed in the dilated lymph vessels of bronchial and bronchiolar wall in the lungs. The worms were identified as Filaroides osleri based on the parasitological examinations.
