Dog Cognitive Decline Early Detection

Canine cognitive dysfunction syndrome is the dog equivalent of dementia and requires early detection and management to maintain quality of life.

Key Facts

CDS affects 14-35% of dogs over 8 years old and increases with age
Early signs include disorientation, sleep disturbance, and house soiling
Diagnosis is clinical - no definitive test exists, making owner observation critical
Selegiline and dietary supplements may slow progression in some dogs
Environmental enrichment and maintaining routine support dogs with CDS

Welfare Considerations

Cognitive decline causes confusion, anxiety, and loss of the capacity to navigate familiar environments. Dogs with CDS may no longer recognize their owners. Early detection allows management that slows progression and maintains quality of life longer.

What You Can Do

Use validated CDS screening questionnaires annually from age 8 for dogs
Report changes in sleep, orientation, or behavior to your vet promptly
Maintain consistent routines and familiar environments for dogs with CDS
