Plain-English summary
A 9-year-old spayed female German Shepherd was brought in after experiencing rapid breathing and collapsing. The vet found that she had a serious heart issue caused by severe bleeding from a splenic tumor (hemangiosarcoma). An ultrasound confirmed the tumor and fluid buildup in her abdomen. After surgery to remove the spleen and a blood transfusion, her heart problems improved, and she was able to breathe normally again.

Abstract
Dynamic left ventricular outflow tract obstruction (DLVOTO) is a common condition in cats and humans. In this case report, a dog is described with DLVOTO secondary to severe intra-abdominal hemorrhage caused by a hemangiosarcoma. The dog was a 9-year-old, 35.7-kg, spayed female German Shepard dog that presented with a history of tachypnea and collapse. A Levine II/VI systolic murmur was present at the heart base. Abdominal ultrasonography revealed a splenic mass and a large amount of ascites. Echocardiography showed a reduced left ventricular diameter and an increased aortic velocity caused by systolic anterior motion (SAM) of the mitral valve apparatus. The heart murmur and the SAM were resolved after treatment including a splenectomy and a blood transfusion.
