Senior Dog Quality of Life Assessment

Structured quality of life assessment tools help owners and veterinarians make informed decisions for senior dogs, including when intervention or euthanasia best serves the animal's welfare.

Key Facts

The Zoetis Quality of Life Scale and HHHHHMM Scale provide structured frameworks for assessing senior dog welfare
Pain, mobility, and social interaction are the strongest predictors of quality of life in older dogs
Cognitive dysfunction syndrome affects up to 68% of dogs aged 15-16, profoundly affecting welfare and owner relationships
Palliative care for senior dogs focuses on comfort, pain control, and preserving meaningful daily experiences
Studies show owners consistently overestimate their dog's quality of life compared to veterinary assessment

Welfare Considerations

Prolonging life is not always the same as maximizing welfare. For senior dogs with multiple comorbidities, the welfare goal shifts from treatment to comfort, and from longevity to quality of remaining time. Quality of life tools give owners an objective framework to assess whether their dog is having more good days than bad - and to make the compassionate decision for euthanasia before suffering becomes severe.
