Hemangiosarcoma of the skin in a dog. Hemangiosarcoma is quite common in dogs, and more so in certain breeds including German Shepherds and Golden Retrievers.

In about one fifth of the dogs with a mastocytoma, feeding instability, vomiting, tarry stools and anemia occur as a result of gastric or duodenal ulcers, [10] in autopsies such ulcers are even detected in more than 80% of patients. [18] About 80% of the dogs with such ulcers are euthanized due to poor general condition. [19]
