How this encyclopedia is organised

• Scope — 398 breed monographs in 13 groups and 167 clinical conditions across 19 body systems, plus 24 substantive parts covering biology, behaviour, nutrition, husbandry, puppy raising, senior care, emergencies, breeding ethics, working dogs, cognition, complementary therapies, evolution, genetics, toxicology, regional wildlife, rabies and zoonoses, the cost of care and insurance, travel, housing and the law, and how to read a vet's report.
• Part II (Breeds) — one monograph per breed, on a fixed 10-field schema plus a review-status line. Breeds are grouped by function and by region, and no region leads: native and landrace breeds from every continent are documented with the same seriousness as the internationally-recognised pedigree breeds, including landraces the existing references serve poorly.
• Part III (Health and disease) — conditions grouped by body system. Each entry is a name and a plain-language description with the relevant regional and environmental context called out.
• Global in scope, with region-specific practical chapters retained as first-class reference — climate, regulation, veterinary infrastructure, and free-roaming-dog realities — rather than dropped or buried in an appendix.
• Every claim is either cross-referenced to a publicly verifiable source, marked DRAFT — VET REVIEW PENDING, or flagged as a matter of clinical judgement rather than settled fact.
