Genetic indicators
COI — inbreeding
17.19%
High. Common ancestors: Koujinryuu Go Tosa Kuroshiosou, Shushukomachi Go Shinano Monjusou, Chiyotatsumaru Go Sanuki Mizumotosou.
AVK — distinct ancestors
54.8%
34 distinct ancestors out of 62 possible. Among known ancestors only: 58.6%.
Pedigree completeness
93.5%
4 empty slots. The AVK takes them into account, so read both figures together.
Value for the breed's diversity
Very common lines — rarer than 4% of the Shiba born in the last 15 years (since 2012)
How often its ancestors (over 8 generations) appear in the pedigrees of the 11,218 recent dogs: rare lines bring new genes to the breed. Over: 6 generations 8 generations 10 generations
Common ancestors and how they connect 3
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 |
|---|---|---|---|
| Koujinryuu Go Tosa Kuroshiosou ♂ | gen. 2 | gen. 2 | 12.5% |
| Shushukomachi Go Shinano Monjusou ♀ | gen. 3 | gen. 3 | 3.13% |
| Chiyotatsumaru Go Sanuki Mizumotosou ♂ | gen. 3 | gen. 4 | 1.56% |

How the lines connect
Only the dogs that lead to a common ancestor are drawn. Each coloured line goes from a common ancestor down to its descendants. Click a dog to open its page.

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.
