Hemangiosarcoma in dogs: symptoms and treatment

Hemangiosarcoma in dogs is a malignant tumor that develops in the cells of the vascular endothelium and has a high mortality rate.

It is especially worrying because it is quite common – up to ten times more common than other neoplasms.

This is a type of cancer that appears in different ways, and the symptoms and treatments will vary depending on the type and location.

Symptoms of hemangiosarcoma in dogs

The symptoms will vary depending on where the tumor is located. However, there are general warning signs, including anorexia, loss of appetite, acute lack of energy and difficulty moving.

You must of course talk to a veterinarian if you think your animal is affected. Only an expert can examine the animal and rule out other diseases with similar symptoms.

One must pay attention to the basic signs so that the disease does not have time to develop too long before treatment begins.

In many cases, hemangiosarcoma in dogs leads  to varying degrees of bleeding. They can be anything from mild to extreme, which in the worst case can endanger the animal’s life.

However, the symptoms are different when a hemangiosarcoma affects the heart. This is because it either causes vascular obstruction or pericardial effusion that blocks the arteries.


Hemangiosarcoma in dogs has several  action plans that provide guidelines for how to treat this form of cancer.

What veterinarians agree on is that the most urgent action is to remove the tumor through surgery. This is very important if the heart is affected because the arteries can be completely blocked.

Dogs undergo surgery for hemangiosarcoma in dogs

Chemotherapy, or chemotherapy, is the second step, and research shows that dogs undergoing this form of treatment after surgery have a higher chance of survival.

There are other types of hemangiosarcoma, such as in the liver. However, there is great controversy regarding the use of chemotherapy to eliminate it.

At the moment, the most common type is doxorubicin, but other variants are equally promising.

Research also shows that the chances of success increase significantly if the dog gets a good diet. This is because the immune system varies greatly depending on the nutrient intake. The dog will need strength to cope with the treatment.


As with all types of cancer, intervention in time is what makes the difference between life and death. You need to pay close attention to the possible symptoms of these types of diseases.

Delaying the treatment of a disease of this type is likely to result in death as the cancer spreads in the body.

This condition is more common in older dogs and usually appears after the age of ten. However, there are also cases where younger dogs are affected.

The most affected breeds are German Shepherd, Golden Retriever and Boxer. However, no dog breed is immune.
