Overview of Canine Hemangiosarcoma. Hemangiosarcoma is a malignant cancer of the cells that form blood vessels. Because these tumors start in blood vessels, they are frequently filled with blood. Consequently, when a blood-filled tumor ruptures, it can cause problems with internal or external bleeding.
Causes of Retinal Hemorrhage in Dogs. 1  Some congenital deformities of the eye predispose the retina to bleeding in the dog, particularly if the defects involve the retinal blood vessels or areas adjacent to the blood vessels. 2  Circulatory disorders that affect blood vessels may also cause retinal hemorrhages. Examples include high blood pressure (hypertension), too much circulating protein in the blood (hyperviscosity syndrome), weakening of the blood vessels from kidney or adrenal gland disease, and sugar diabetes.
