Japanese Spitz Foundation pedigree database

Find a dog

Search by name in the box above. Accents are optional — tahtihovin finds TÄHTIHOVIN, and the other way round.

Names for the same dog often differ between national registers, and sometimes between a register and the pedigree document itself. Where sources disagree, this database follows a fixed order: the studbook of the country of origin first, then the pedigree as scanned, and only then the studbook of the country where the dog is registered now. If a name you know is not here, try another spelling of it before concluding the dog is missing.

The name also identifies the dog here. Where the same name has been used for more than one dog, the year of birth is added to tell them apart — for example GODDESS OF IWAKI T.M.K. FCI (2018).

What each page shows

A four-generation pedigree. The dog’s own offspring, grouped by mate. Its full siblings. And whatever DNA test results are on record, shown exactly as recorded.

Every one of the 63,778 dogs has a page, however little is known about it — a founder with no recorded parents is in here too.

Reading a pedigree

Colour marks an ancestor that appears more than once in the same pedigree — line-breeding. Each repeated dog has its own tint, and the stronger the colour, the larger the share of the blood that dog contributes. A chart with no colour in it has no ancestor doubled up.

A name that is a link has a record of its own, and that record has its own pedigree behind it. A name in plain text is recorded only as the parent of the dog beside it — the register knows the name and nothing further.

An empty box is a position with no ancestor recorded. Every pedigree is drawn to four generations whether or not the records reach that far, so a short line is visibly short rather than quietly cropped.

Current state

This is the international version of the pedigree data the Japanese Spitz Foundation has collected over the years — thank you to everyone who contributed. We keep collecting information about dogs and adding more tools for breeders.

Available now (September 2026):

• Search by name.
• A page for every dog: four-generation pedigree, offspring grouped by mate, full siblings and DNA test results.
• Linebreeding — which ancestors appear on both the sire’s and the dam’s side of a pedigree, how close up they sit, and how much of the dog they account for between them.
• Foundation reports — which of the breed’s founding dogs stand behind a pedigree, and in what proportion each of them contributed.

Links to both reports are on every dog page.

Planned:

• Photographs of the dogs, once the right to publish each one has been settled.
• Catalogue pages gathering dogs by kennel, birth year, country and DNA test.
• An index of kennels by country, and of litters by year.
• Hypothetical matings — choose a sire and a dam that have never been bred together and see the pedigree their puppies would have, its inbreeding coefficient, and a warning where both parents carry the same recessive DNA result.
• DNA test reports — for a chosen test, how the whole population divides between clear, carrier and affected, and which dogs make up each group.
• Breeder accounts — for announcing planned litters.
