Canine Hemangiosarcomas, also known as malignant hemangioendotheliomas,
angiosarcomas, endotheliosarcomas, account for up to 40% of all abdominal tumors
and are predominant in dogs. This neoplasia tends to be highly malignant and most
patients usually have metastases at the time the diagnosis is made. The usual poor

Further aim was to investigate, if a suspected diagnosis may be based on the
