Canine Health Screening
Dog Cognitive Decline Calculator
Assess your dog for signs of Canine Cognitive Dysfunction (canine dementia) using a vet-recognised behavioural screening framework. Answer honestly based on the last few weeks.
Overview
Canine Cognitive Dysfunction (CCD) — often called canine dementia — is a progressive, age-related decline in a dog's memory, awareness, and behaviour. It shares many parallels with Alzheimer's disease in humans and becomes increasingly common as dogs enter their senior and geriatric years.
This calculator is a screening aid for dog owners. It walks you through the same behavioural signs veterinarians look for, grouped into six recognised categories, and turns your answers into a clear severity score. It is designed for owners of ageing dogs who have noticed subtle changes and want a structured way to gauge whether those changes warrant a professional conversation.
How It Works
- Enter your dog's age in years.
- Read each of the 12 behaviour statements and select how often it applies: Never, Occasionally, Frequently, or Almost always.
- Base your answers on the past few weeks, and consider whether each behaviour is a genuine change from how your dog used to be.
- Click Calculate Result to see your total score, a severity band, and a breakdown across the six behaviour areas.
- Use the guidance provided to decide on next steps. Click Reset to start over.
Formula & Scoring Explanation
The tool uses a DISHAA-aligned model — the framework vets use to assess cognitive dysfunction. Behaviours fall into six areas: Disorientation, Interactions, Sleep–wake cycle, House-soiling & memory, Activity, and Anxiety.
Never = 0 · Occasionally = 1 · Frequently = 2 · Almost always = 3
12 questions × max 3 points = 36 maximum
Your total is mapped to a severity band:
| Score | Band | What it suggests |
|---|---|---|
| 0–4 | Minimal | Within the normal range for an ageing dog |
| 5–12 | Mild | Early or subtle changes — worth monitoring |
| 13–22 | Moderate | A pattern consistent with CCD — see your vet |
| 23–36 | Significant | Strong indication — prompt veterinary assessment |
The score is driven by behaviour, not age, because that is how CCD is actually screened. Age is used only to add interpretive context, since prevalence rises steeply in older dogs.
Practical Benefits
Early recognition matters. While CCD cannot be cured, dogs identified early often respond well to interventions — diet changes, supplements, environmental enrichment, and medication — that can slow progression and improve quality of life.
This tool helps you: spot changes you might otherwise dismiss as "just old age"; organise vague concerns into concrete, describable observations; arrive at your vet appointment with a structured summary instead of guesswork; and track your dog over time by re-running the assessment every few months to see whether scores are climbing.
