Osteosarcoma in Dogs

Osteosarcoma refers to the most common bone tumor found in dogs. Bone cancer can affect any breed of dog, but it is more commonly found in the larger breeds. The disease is extremely aggressive and has a tendency to spread rapidly into other parts of the dog’s body (metastasize). There are treatment options available, but generally the long term prognosis for the animal is poor.

Symptoms and Types

Many signs of bone cancer are subtle. They can include swelling, lameness, and joint or bone pain. In some cases, dogs suffering from bone cancer will appear tired or have anorexia. Occasionally, dogs will exhibit a mass growth on their body or a painful inflammation around the sight of the tumor.


Current knowledge of the disease has not linked genetics or gender to the condition, but bone cancer does appear more often in large to giant breeds of dogs. Some studies have shown a slight increase in the development of osteosarcoma among dogs that have experienced a blunt bone injury.


A veterinarian will use X-rays to view the mass, often using several angles to get an accurate picture. Other tests include biopsies, blood tests, bone scans, and CAT scans to view the bone areas, and the mass, if discovered. If the diagnosis is bone cancer, it is important to note that the prognosis can often be unfavorable and that there are numerous side effects to the treatment options (side affects that can often but not always be mitigated with concentrated nutritional support – see below). Management on the pet pwner’s part will be required.
