Genetic indicators
COI — inbreeding
1.37%
Low. Common ancestor: Tenshouriki Go Fudougataki Kensha.
AVK — distinct ancestors
64.5%
40 distinct ancestors out of 62 possible. Among known ancestors only: 74.1%.
Pedigree completeness
87.1%
8 empty slots. The AVK takes them into account, so read both figures together.
Value for the breed's diversity
Very common pedigree — rarer than 5% of the Shiba born in the last 15 years (since 2012)
How often its ancestors (over 10 generations) appear in the pedigrees of the 11,017 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 1
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 |
|---|---|---|---|
| Tenshouriki Go Fudougataki Kensha ♂ | gen. 4 ×3gen. 5 | gen. 5 | 1.37% |
| COI over 5 generations | 1.37% | ||
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.
