Three Yorkshire Terriers (12-year-old, 13-year-old, and 15-year-old castrated males) with respiratory distress,coughing and anorexia were the subjects of this report. In laboratory examinations, there were no remarkable findings. However, the thoracic radiographic findings included a large mass of soft tissue density in the cardiac base region,tracheal elevation, and aortic bulging in all three Yorkshire Terriers. There were no remarkable findings in the abdominalradiographs. In echocardiography, a homogeneous hyperechoic mass around the aorta and bicuspid valve regurgitationwere found in all three dogs. There were no remarkable findings in abdominal ultrasonography. Computed tomographicfindings showed a large well -defined heterogeneous mass in the cranial vena cava, which was dominant in the leftside in all three Yorkshire Terriers. The mass sizes were about 3 × 4 cm. In post-contrast scanning, contrast enhancementwas evident. These cases were diagnosed as heart-base tumor. Treatments provided to the three dogs were based onsymptomatic medical management of cardiac failure and tracheal collapse. Case 1 (12-year-old) survived for 3 months,case 2 (13-year-old) for 5 months, and case 3 (15-year-old) for 32 months after the diagnosis. Our results show thatthe clinical findings, thoracic radiography, echocardiography, computed tomography (CT) and symptomatic medicalmanagement in dogs suspected to have heart base tumor.
