Canine Cognitive Dysfunction: Supporting Aging Dogs

Canine cognitive dysfunction — the dog equivalent of Alzheimer's disease — affects a significant proportion of older dogs. Recognition and management can significantly improve quality of life in their final years.

Key Facts

Approximately 28% of dogs aged 11-12 show signs of CCD; 68% of dogs 15-16 are affected
Signs include disorientation, disrupted sleep-wake cycles, house soiling, and reduced interaction
The condition is progressive but management can slow progression and improve welfare significantly
Enrichment, dietary supplements, and medications including selegiline improve outcomes
Early recognition through DISHA assessment (Disorientation, Interactions, Sleep, Housetraining, Activity) enables earlier intervention

Welfare Considerations

A dog with unrecognised CCD experiencing nighttime confusion, inability to navigate familiar spaces, and loss of learned behaviours is suffering significantly. Owners who attribute these to normal aging miss opportunities for meaningful intervention. Treatment does not cure but can slow progression and improve comfort — making a significant difference to years of life quality.

What You Can Do

Learn the DISHA signs and monitor older dogs proactively from age 7-8 onwards
Discuss CCD screening with your vet at annual check-ups for dogs over 8
Provide environmental enrichment and mental stimulation to support cognitive health
Consult a veterinary neurologist if CCD is suspected — management options have expanded significantly
