Canine Cognitive Dysfunction (CCD) is far more common than most owners realise—studies suggest it affects over 50% of dogs aged 11 and above. Often dismissed as "just getting old," CCD is a distinct neurological condition with identifiable symptoms and evidence-based management strategies. Early recognition is key because interventions are most effective when started early.
Quick take
- Canine Cognitive Dysfunction (CCD) affects over 50% of dogs aged 11+.
- Early signs include disorientation, sleep changes, and altered social behaviour.
- Mental enrichment, diet, and specific supplements may slow progression.
- CCD is under-diagnosed because owners assume it's 'just old age.'
What Is Canine Cognitive Dysfunction?
CCD is a neurodegenerative condition analogous to Alzheimer's disease in humans. It involves the accumulation of beta-amyloid plaques in the brain, oxidative damage, and reduced neurotransmitter function. The result is a progressive decline in memory, learning, awareness, and responsiveness to stimuli.
The DISHA Framework: Recognising Early Signs
Veterinarians use the DISHA acronym to identify CCD: Disorientation (getting stuck in corners, staring at walls); Interaction changes (less interest in greeting, altered social behaviour); Sleep-wake cycle disruption (pacing at night, sleeping more during the day); House soiling (in previously housetrained dogs); and Activity changes (restlessness or apathy, repetitive behaviours).
Mental Enrichment Strategies
Regular cognitive stimulation can help maintain neural pathways. Puzzle feeders, scent games, new walking routes, basic training refreshers, and social interaction all provide mental exercise. Even 10–15 minutes of structured enrichment daily can be beneficial. The key is variety—rotate activities to provide novel challenges.

Nutritional and Supplement Support
Diets enriched with antioxidants, B vitamins, and medium-chain triglycerides (MCTs) have shown some benefit in clinical trials. SAMe supplementation may support neurotransmitter function. Omega-3 fatty acids, particularly DHA, play a role in brain cell membrane health. Discuss specific options with your vet.
When to Seek Professional Assessment
If you notice two or more DISHA signs, discuss them with your veterinarian. Early assessment allows for baseline cognitive evaluation and timely intervention. Your vet may recommend a cognitive assessment questionnaire, blood work to rule out other causes, and a management plan.
What to Do This Week
Run through the DISHA checklist this week, noting any signs you've observed. Start one new enrichment activity—a puzzle feeder or a scent game using hidden treats—and observe how your dog responds. Record your observations in your Longevity Scorecard.
When to See a Vet Urgently
Seek veterinary attention promptly if your dog shows sudden onset confusion, circling, head pressing against walls, seizures, sudden vision or hearing loss, or dramatic changes in personality or behaviour over days rather than weeks.
