The Nihon Ken Hozonkai (日本犬保存会 , The Association for the Preservation of the Japanese Dog ) , commonly abbreviated to Nippo, is a preserver and maintainer of the registries for the six native Japanese dog breeds: the Akita Inu, Hokkaido, Kai Ken, Kishu, Shikoku, and Shiba Inu.
 Nippo also issues the Nippo Standard, which serves as a breed standard for the six native breeds.
Pusuke (プースケ "in katakana or" ぷうすけ "in hiragana", 1 April 1985 – 5 December 2011) was a Japanese Shiba Inu who, according to the "Guinness World Records", was the world's oldest dog from December 2010 until his death in December 2011.

The Boxer is a medium-sized, short-haired breed of dog, developed in Germany.
 The coat is smooth and tight-fitting; colours are fawn or brindled, with or without white markings, and white.
 Boxers are brachycephalic (they have broad, short skulls), have a square muzzle, mandibular prognathism (an underbite), very strong jaws, and a powerful bite ideal for hanging on to large prey.
 The Boxer was bred from the Old English Bulldog and the now extinct Bullenbeisser which became extinct by crossbreeding rather than by a decadence of the breed.
 The purpose of the crossbreeding was the wish to eliminate the excessive white color of the breed, and the necessity of producing thousands of dogs for one of the most popular breeds in the world.
 The Boxer is part of the Molosser group.
 This group is a category of solidly built, large dog breeds that all descend from the same common ancestor, the large shepherd dog known as a Molossus.
 The Boxer is a member of the Working Group.
The Leonberger is a giant dog breed.
 The breed's name derives from the city of Leonberg in Baden-Württemberg, Germany.
 According to legend, the Leonberger was ostensibly bred as a "symbolic dog" that would mimic the lion in the town crest.
 It is in the Working Group for dog shows such as Crufts, but not at the World Dog Show.

The Shikoku (四国犬 , Shikoku-ken , alternative names: Kochi-ken, Mikawa Inu, Japanese Wolfdog) is a native, primitive Japanese breed of dog from Shikoku island that is similar to a Shiba Inu.
