Test a mating
Choose a sire and a dam to preview the pedigree and inbreeding of their future litter. You can also imagine a puppy that does not exist yet, from its two parents, and test its own mating.
Genetic indicators of the litter

Value of this litter for the breed's diversity
Common pedigree — the puppies would be rarer than 35% of the Shiba born in the last 15 years (since 2012)
Litter: 35% ♂ Sire: Very common pedigree · 13% ♀ Dam: Common pedigree · 25%
How often the puppies' ancestors (over 6 generations) appear in the pedigrees of the 11,487 recent dogs: using dogs with a rare pedigree helps keep diversity in the breed.
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 |
|---|---|---|---|
| Taihei no Chihiro go Sapporo Kagasou ♀ | gen. 2 | gen. 3 | 7.03% |
| COI over 5 generations | 7.03% | ||
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.
