Companion Animal Ageing and Quality of Life

As companion animals live longer, managing the ageing process with attention to quality of life becomes increasingly important. Evidence-based geriatric care improves welfare significantly.

Key Facts

Dogs and cats are living 20-25% longer than they did 30 years ago due to veterinary advances
The geriatric life stage begins at 7-10 years in dogs and 10-12 years in cats
Quality of life scales for companion animals (e.g. HHHHHMM scale) help owners assess welfare objectively
Pain is the most common and undertreated welfare problem in geriatric companion animals
Cognitive dysfunction syndrome affects over 60% of dogs over 15 and 35% of cats over 11

Welfare Considerations

Extending lifespan without maintaining quality of life causes more suffering, not less. Geriatric companion animals require proactive pain management, cognitive support, adjusted nutrition and environmental modification. The HHHHHMM scale (Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, More good days than bad) provides a structured framework for families facing end-of-life decisions. Palliative and hospice care for companion animals is a growing field that enables comfortable final stages. Euthanasia when quality of life cannot be maintained is a welfare gift, not a failure.

What You Can Do

Use a validated quality of life scale monthly from age 10 in dogs, 12 in cats
Schedule 6-monthly geriatric health checks including pain assessment from appropriate age
Discuss pain management with your vet - many geriatric animals benefit from multimodal analgesia
Modify the home environment: ramps, orthopaedic beds, raised food bowls for comfort
Engage with palliative care services if available to maximise quality of final months
