Validated quality of life tools help owners and vets make welfare-centered decisions for dogs with cancer. Understanding these tools guides their application in practice.
Quality of life assessment for dogs with cancer is a welfare tool that transforms a deeply emotional decision into one guided by evidence. Owners are often unable to objectively assess their dog's quality of life because of grief, hope, and the human tendency to anthropomorphize expressions of contentment. Validated scales provide a framework that captures what matters for dog welfare — pain, mobility, enjoyment of life — and tracks changes over time. This guides decisions about when treatment is helping versus when palliative or end-of-life care better serves the dog's welfare.
