Value for the breed's diversity

Rare pedigree — rarer than 96% of the Shiba born in the last 15 years (since 2012)

How often its ancestors (over 6 generations) appear in the pedigrees of the 11,571 recent dogs: using dogs with a rare pedigree helps keep diversity in the breed. Over: 6 generations 8 generations 10 generations

Common ancestors and how they connect 2

Over 5 generations: each ancestor found on both the sire's and the dam's side, and what it adds to the COI.

Ancestor	Sire's side	Dam's side	Share of the COI
Natural Mariko ♀	gen. 2	gen. 3	6.25%
Vulpecula Nozami ♂	gen. 3	gen. 3gen. 4	3.13%
COI over 5 generations			9.38%

How these figures are calculated

COI — Wright's formula: F = Σ (½)^n₁+n₂+1 × (1 + F_A), summed over every path through a common ancestor A. The number of generations must be fixed for two dogs to be comparable: a more complete pedigree mechanically raises the figure.

AVK — distinct ancestors divided by the theoretical number of ancestors. Over 5 generations there are 62 possible slots. 100% means no ancestor appears twice.

Completeness — the share of slots actually filled in. The AVK is misleading without it: a half-empty pedigree shows a low AVK even with no inbreeding at all, simply because data is missing.
