Dog Welfare: Senior Cognitive Dysfunction Syndrome

Canine cognitive dysfunction syndrome (CDS) is the most common neurodegenerative condition in older dogs. Understanding it improves recognition and management.

Key Facts

CDS affects an estimated 22-68% of dogs over 15 years old, depending on diagnostic criteria
Clinical signs include disorientation, changed sleep-wake cycles, reduced interaction, and house soiling
The condition is underdiagnosed - owners often attribute signs to normal ageing
Selegiline (Anipryl) is licensed for CDS in many countries and can improve clinical signs
Environmental enrichment, dietary antioxidants, and physical exercise have supportive welfare benefits
Early recognition enables earlier intervention and better quality of life management

Welfare Considerations

Canine cognitive dysfunction syndrome causes genuine suffering through disorientation, anxiety, disrupted sleep, and loss of learned behaviours. Many affected dogs are unknowingly left to deteriorate when effective management is available. The welfare impact is compounded by the dog's inability to understand or communicate what is happening to them, while owners attribute changes to normal ageing. Proactive cognitive health screening in dogs over 9-10 years should be standard veterinary practice. When diagnosed, a multimodal approach combining medication, enrichment, dietary support, and environmental adaptation can significantly improve quality of life.

What You Can Do

Learn the signs of canine cognitive dysfunction - disorientation, changed sleep, reduced interaction
Request cognitive health assessment for dogs over 9 years at annual checks
Discuss management options with your vet if CDS is suspected - treatment is available
Support research into canine cognitive ageing and neuroprotective interventions
