Plain-English summary
A 7-year-old male Labrador retriever was brought to the vet after vomiting for 24 hours and showing signs of fever and rapid heart rate. X-rays showed that his heart was enlarged and there were fluid issues in his lungs. Despite starting treatment for heart failure, his condition worsened, and an ultrasound revealed a large growth on his heart valve. Sadly, the dog was euthanized due to his poor health, and a post-mortem examination found that the growth was an osteosarcoma (a type of bone cancer) on the heart valve.

Abstract
A 7 yr old castrated male Labrador retriever (35.6 kg) was evaluated for an acute onset of vomiting of 24 hr duration. On initial examination, the patient was febrile (103.8°F) and tachycardic (150 beats/min). Thoracic radiographs revealed left atrial enlargement with mild pulmonary infiltrates. The dog's condition worsened and repeat radiographs revealed worsening pulmonary infiltrates and pleural effusion. Treatment for heart failure was initiated. An echocardiogram showed a large 3 cm × 4 cm vegetation on the atrial surface of the posterior mitral valve. The patient was euthanized due to poor clinical appearance and infective endocarditis was suspected. Necropsy revealed an osteosarcoma of the posterior mitral valve, which cultured negative.
