Canine Cancer Welfare Management: Quality of Life Approach

Cancer is the leading cause of death in dogs over 10 years old, and welfare-focused management requires honest assessment of quality of life rather than treatment at all costs.

Key Facts

Cancer causes approximately 50% of deaths in dogs over 10 years
Common canine cancers include lymphoma, osteosarcoma, mast cell tumour, and haemangiosarcoma
Pain management is a core component of welfare-centred cancer care
Many treatments extend survival but may reduce short-term quality of life
Palliative care options can provide excellent welfare without curative intent
Quality of life scales including the HHHHHMM scale help guide end-of-life decisions

Welfare Considerations

Dogs with cancer experience pain, fatigue, and in advanced disease, significant suffering. Aggressive treatment can extend life but may reduce quality of life during treatment. Palliative care focused on pain control, nausea management, and comfort can provide excellent welfare for months. The welfare-centred approach requires honest, evidence-informed conversations about prognosis and quality of life.

What You Can Do

Seek referral to a veterinary oncologist for any cancer diagnosis
Discuss quality of life assessment frameworks with your vet from diagnosis onwards
Ensure adequate pain management is central to any treatment plan
Use a structured quality of life assessment tool monthly to track changes
Plan euthanasia before severe suffering occurs rather than waiting for crisis
Consider joining clinical trials which provide access to treatments and contribute research
