Plain-English summary
A 5-year-old cross-bred dog was brought in for coughing and collapsing during exercise over the past few weeks. X-rays showed an enlarged heart and a suspicious area near the heart, while an ultrasound revealed a mass in the pulmonary artery. Unfortunately, the owners chose not to pursue further tests, and the dog passed away just four days later. A postmortem examination confirmed the presence of a chondrosarcoma, a type of tumor, in the pulmonary artery. This case highlights a rare cause of fainting in dogs.

Abstract
A 5-year-old cross-bred dog was examined with an 8-week history of coughing and a 3-week history of collapsing during exercise. Thoracic radiography revealed moderate right-sided cardiomegaly and a partially mineralized area over the dorsocranial heart base. Echocardiography demonstrated moderate eccentric and concentric right ventricular hypertrophy and a hypoechoic mass in the main pulmonary artery. The owners declined further investigations and the dog died at home 4 days later. Postmortem revealed a primary pulmonary artery chondrosarcoma. This is the first case report of a pulmonary artery chondrosarcoma in a dog and presents another differential diagnosis of syncope in the dog.
