A female French bulldog was admitted to our veterinary hospital with symptoms of dyspnea and syncope seven days after an ovariohysterectomy for pyometra. On the first visit, cardiomegaly, a tumor-like mass on the pulmonary valve (15.0×5.8 mm), pulmonary valve stenosis, pulmonary arterial dilatation, and tricuspid regurgitation were observed. The clinical signs were improved with medication. On the 9th day, the dog was brought back to the hospital in an unconscious state. The mass on the pulmonary valve had increased in size (18.5×13.0 mm) and was observed to severely constrict the pulmonary valve. The dog suffered a cardiac arrest on the 12th day. The mass on the pulmonary valve was evaluated histopathologically as vegetation related to bacterial purulent pulmonary arteritis. We diagnosed it as a rare case of canine pulmonary valve infective endocarditis.
