Genetic indicators
The three figures are recalculated for the generations chosen.

COI — inbreeding

7.03%

Moderate. Common ancestors: San Jo Proud Mary, Tenkei Go Etchuu Wakasugisou, Arisa Go Etchuu Wakasugisou.

AVK — distinct ancestors

72.6%

45 distinct ancestors out of 62 possible. Among known ancestors only: 78.9%.

Pedigree completeness

91.9%

5 empty slots. The AVK takes them into account, so read both figures together.

Value for the breed's diversity

Average pedigree — rarer than 62% of the Shiba born in the last 15 years (since 2012)

How often its ancestors (over 8 generations) appear in the pedigrees of the 11,365 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 3

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

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.
