Osteosarcoma in Dogs
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 site 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.
Your 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 is often unfavorable and that there are numerous side effects to the treatment options. Management on your part will be required.
