Value for the breed's diversity
Rare pedigree — rarer than 94% 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 |
|---|---|---|---|
| Tanasea's Taimatsu ♂ | gen. 1 | gen. 3 | 12.5% |
| Tanasea's Torch of Zen ♀ | gen. 2 | gen. 4 ×2 | 3.13% |
| COI over 5 generations | 15.63% | ||

How these figures are calculated
COI — Wright's formula: F = Σ (½)n₁+n₂+1 × (1 + FA), 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.
