End-of-Life Care for Companion Animals: Welfare and Decision-Making

The decision to euthanise a beloved companion animal is among the most emotionally difficult facing pet owners, and welfare science can help guide timing to minimise suffering.

Key Facts

Approximately 2.5 million companion animals are euthanised in the UK annually
Owner-reported quality-of-life assessments are validated tools for end-of-life decision-making
The Zoetis quality-of-life scale (HHHHHMM) assesses hurt, hunger, hydration, hygiene, happiness, mobility and more moments than bad
Pain-free palliative care has expanded options for extended quality time before euthanasia
Veterinary palliative medicine is now a recognised specialty in the US and growing elsewhere

Welfare Considerations

Delaying euthanasia beyond the point of adequate quality of life is a welfare harm as real as any other form of animal suffering — yet owner attachment frequently leads to prolonged suffering out of reluctance to let go. Conversely, premature euthanasia deprives animals of quality time they still have available. Quality-of-life assessment tools give owners an objective framework for evaluating their pet's experience rather than relying on emotionally coloured perception. Veterinary professionals who communicate proactively about palliative options and quality-of-life thresholds serve animal welfare as fundamentally as any other clinical intervention.
