Dog Canine Cancer Quality of Life

Cancer is the leading cause of death in older dogs, requiring careful quality of life assessment alongside treatment decisions.

Key Facts

Osteosarcoma, lymphoma, mast cell tumours, and hemangiosarcoma are among the most common
Palliative care options including pain management can maintain quality of life when cure is not possible
The HHHHHMM scale helps owners assess quality of life across pain, hunger, hydration, and happiness domains

Welfare Considerations

Dogs with cancer experience suffering from both the disease and from treatments. Honest quality of life assessment, compassionate decision-making, and excellent palliative care are the most important welfare priorities.

What You Can Do

Use validated quality of life assessment tools to guide decision-making
Book annual or twice-yearly wellness visits in senior dogs for early cancer detection
