Dog Senior Cognitive Dysfunction Quality of Life

Canine cognitive dysfunction syndrome (CDS) is under-diagnosed and causes real suffering in elderly dogs - management can maintain quality of life.

Key Facts

Over 50% of dogs over 11 years old show signs of cognitive dysfunction
DISHA signs (Disorientation, Interaction changes, Sleep-wake changes, House soiling, Activity changes) guide diagnosis
Selegiline and propentofylline have evidence for slowing cognitive decline
Environmental enrichment and regular gentle exercise support cognitive function
Omega-3 fatty acid supplementation and antioxidant-enriched diets may slow progression

Welfare Considerations

Cognitive dysfunction causes confusion, anxiety, and distress in elderly dogs. Early diagnosis and active management - including medication, enrichment, and senior-appropriate care - extend comfortable, good-quality life.

What You Can Do

Discuss cognitive dysfunction screening with your vet for dogs over 10 years old
Provide regular, gentle mental stimulation and exercise appropriate for senior dogs
Use nightlights for disoriented dogs and maintain consistent daily routines
