A geriatric German shepherd dog was presented for indigestion and ascites. The dog was lethargic, had tachycardia with intermittent vomiting, episodes of weakness, occasional pulse deficits, and anorexia. Radiography, ultrasonography, quick assessment tests, and a complete blood (cell) count (CBC)/biochemistry panel indicated internal hemorrhage and potential problems with hemostasis. The dog was euthanized. A necropsy, with histopathology confirmed diagnosis of splenic hemangiosarcoma.
