How the Global Dog Ownership Index Works

Purpose and boundaries

The Index compares practical conditions that shape dog ownership and care. It does not measure dog happiness, identify a universally preferred country, guarantee access, or replace legal, veterinary, housing or travel advice. The founding countries are Australia, Italy, South Africa, the United Kingdom and the United States.

Eight categories and category-specific rubrics

Editorial scale

Equal weighting and overall calculation

Each category contributes 12.5%. The visible formula is:

Overall editorial score = (C₁ + C₂ + C₃ + C₄ + C₅ + C₆ + C₇ + C₈) ÷ 8

The result is rounded to one decimal. Bands are 1.0–1.7 substantial barriers; 1.8–2.5 notable constraints; 2.6–3.4 mixed conditions; 3.5–4.2 generally supportive; and 4.3–5.0 broadly supportive.

Fictional example

Country A scores 3 in all eight categories, producing 3.0. Country B alternates between 2 and 4 across four categories each, also producing 3.0. The equal totals conceal different trade-offs, which is why category rationales and personal priorities matter.

Missing-data rules

A category may use score: null and display “Evidence still being reviewed”. Missing evidence is never zero. An overall score is calculated only when all eight categories have a score, rationale and at least one resolved source. Otherwise the profile displays “Provisional profile — overall score not yet calculated”.

Evidence confidence

High confidence requires recent, direct and geographically appropriate evidence. Moderate confidence covers authoritative but partial evidence or necessary proxies. Limited confidence makes sparse, older or predominantly local evidence explicit. Confidence never changes the score automatically.

Source hierarchy and freshness

Accepted types are government, official statistics, intergovernmental organisations, public regulators, official transport operators, professional organisations, industry associations, academic research and local government. Generic blogs, affiliates, AI summaries, anonymous listicles, scraped snippets and unverified directories are excluded as primary scoring evidence. Source maintenance is documented internally, but no record should be treated as a promise that an underlying rule cannot change.

National-versus-local variation

Representative local evidence is labelled. One city, state or operator is never treated as an entire country. UK jurisdictions, US federalism, Australian states and territories, Italian municipalities and South African municipalities each require explicit care.

Comparability limitations

Costs

Raw currency conversion is not a household cost comparison. Local prices, purchasing power, housing and veterinary access remain different, so the Index does not publish a false universal annual dog cost.

Climate

Climate scoring describes management burden across heat, cold and hazards. It is not a breed-health diagnosis or a declaration that a country is medically safe for every dog.

International travel

Travel scoring is a broad view of process complexity. Actual requirements depend on origin, destination, transit, dog history, purpose and carrier. Use the Passport Planner and re-open official sources.

Editorial judgement, corrections and maintenance

Scores are Dog Haven Group interpretations documented against public rubrics. Assessments are maintained through source checks, documented corrections and validation. Future countries will be published only after complete research, not as public placeholders.
