Osteosarcoma (OSA) is the most common primary bone tumor in dogs, most often affecting the limbs of large and giant breeds. It is an aggressive malignancy that spreads rapidly to the lungs in most cases without treatment. The decisions around staging, surgical approach, and chemotherapy protocol have profound effects on survival time and quality of life.

Staging for metastatic disease, surgical margins, and limb-sparing vs amputation decisions require specialist oncology input. CT staging of the lungs and regional lymph nodes is essential — the presence of detectable metastases at diagnosis significantly changes the calculus. Limb-sparing surgery is only appropriate in specific anatomical locations and carries higher complication rates.
CT staging, limb-sparing candidacy assessment, chemotherapy protocol selection (carboplatin vs doxorubicin alternating), palliative radiation option, and prognosis with vs without treatment. An oncologist provides a complete picture of expected survival time with amputation alone, with amputation plus chemotherapy, and with palliative-only management — allowing informed decision-making.

Not always. Amputation is the most common approach and dogs adapt remarkably well on three legs, but limb-sparing surgery or radiation for pain control are alternatives in selected cases. A specialist can tell you which options genuinely fit your dog.
It varies with treatment. Amputation plus chemotherapy commonly gives a median survival of around a year, while comfort-focused care is shorter. An oncologist can give you honest numbers for your dog's specific situation.
That is a personal decision, and there is no wrong answer. Some families pursue surgery and chemotherapy for more good time, others choose comfort care. A specialist review helps you decide with clear information rather than under pressure.
