What does this mean for a dog with this trait?

There is no known cure for osteosarcoma. The condition may be treated through chemotherapy, which can extend life between 6 months and 1 year. If caught early, surgical amputation may stop the spread of the tumor.

Symptoms

Symptoms of osteosarcoma in Greyhounds typically first appear as signs of pain in a specific limb. Dogs may be reluctant to put pressure on this limb. This may be accompanied by a noticeable mass or swelling of the limb. As the cancer progresses, dogs can experience loss of appetite and difficulty breathing. Unfortunately, the condition often results in death.
