Canine Osteosarcoma: Welfare and Palliative Management

Navigating welfare decisions in dogs with bone cancer, from diagnosis to end of life.

Key Facts

Osteosarcoma accounts for 85% of primary bone tumours in dogs
Large and giant breeds are disproportionately affected — Great Danes, Greyhounds, Rottweilers
Amputation with chemotherapy extends median survival to 10-12 months
Pain management is the central welfare obligation at all disease stages

Welfare Considerations

Osteosarcoma causes intense bone pain that dramatically impairs welfare. Welfare-centred oncology prioritises pain management from diagnosis — NSAIDs, gabapentin, and bisphosphonates all contribute. Amputation removes the pain source and is well-tolerated in most dogs. When owners decline surgery, palliative radiation therapy reduces pain substantially. Quality of life monitoring guides end-of-life decision timing.

What You Can Do

Ensure adequate multi-modal pain management from diagnosis onward
Discuss amputation with your vet — most dogs adapt remarkably well and pain is eliminated
Use quality of life scoring tools regularly to guide honest end-of-life conversations
