Dog breed · Japan
The Shiba Inu (Japanese: 柴犬; Japanese pronunciation: [ɕi.ba.i.nɯ]) is a breed of hunting dog from Japan. A small-to-medium breed, it is the smallest of the six original dog breeds native to Japan. The Shiba Inu was originally bred for hunting. Its name literally translates to "brushwood dog", as it is used to flush game.
The Shiba Inu is a small, alert, and agile dog that copes well with mountainous terrain and hiking trails. Its appearance is similar to other Japanese dog breeds such as the Akita Inu or Hokkaido, but the Shiba Inu is a different breed with a distinct bloodline, temperament, and smaller size than other Japanese dog breeds.
Temperament: The Shiba Inu is considered an alert, affectionate, and independent breed with high intelligence but also somewhat stubborn and strong-willed.
The terms "spirited boldness" (悍威, kan'i), "good nature" (良性, ryōsei), and "artlessness" (素朴, soboku) have subtle interpretations that have been the subject of much commentary.
A survey of experts classified the Shiba Inu as having "high aggression, high reactivity and medium trainability". A possible explanation for this and other observed behaviour is that the Shiba Inu is more closely related to the wolf than domesticated dogs from other countries. Due to the high intelligence of the breed it requires a lot of exercise and stimulation. Insufficient exercise may lead to anxiety which leads to undesirable behaviours, notably the "shiba scream". The Shiba Inu has a reputation for being "aloof" and early socialization as a puppy is key for the dog to get along with other people and animals.
A survey in Japan found the Shiba Inu to be more likely to engage in destructive behaviour, refusal to walk whilst on a lead, engage in mounting behaviour, and tail chasing. The Shiba Inu was also found to be less likely to bark at noises whilst inside the house.
Appearance: The breed's standard colors are red, sesame, black sesame, red sesame (sashige), black and tan, or cream. All have a cream to white ventral color, known as urajiro (裏白). Urajiro literally translates to "underside white". The urajiro is required in the following areas on all coat colors: on the sides of the muzzle, on the cheeks, inside the ears, on the underjaw and upper throat, inside of legs, on the abdomen, around the vent and the ventral side of the tail. On reds: commonly on the throat, fore chest, and chest. On blacks and sesames: commonly as a triangular mark on both sides of the fore chest.
Other than the urajiro areas, the cream color is considered a "major fault" by both the Japan Kennel Club and American Kennel Club. It is not intentionally bred in a show dog, as the required markings are not discernible. However, a cream coat is acceptable according to The Kennel Club (UK) breed standard.
Shiba Inu have a double coat; the topcoat is stiff with guard hairs and the undercoat is soft and plush. Although less common, Shiba Inu can also be long-haired as a result of inheriting the recessive gene from both parents.
Health: A study in Japan on patella luxation in small breeds found the Shiba Inu to have the second highest rate of the condition, with 35% of the Shiba Inus surveyed being affected. Three genes belonging to the breed were associated with glaucoma, as found in an analysis of DNA sequencing. Another study from Japan reviewing cases of dogs presented for ophthalmologic examination found the Shiba Inu to make up 33% of all glaucoma cases whilst only making up 2.7% of the total population used in the study. The Shiba Inu is predisposed to canine atopic dermatitis. An auto-immune disease common in Akitas Vogt-Koyanagi-Harada-like syndrome is known to occur in the Shiba Inu.
Lifespan: A review of cemetery data in Japan found that the Shiba Inu had a life expectancy of 15.5 years, greater than any other breed. A 2024 UK study found a life expectancy of 14.6 years for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreeds.
History: The Shiba Inu has been identified as a basal breed that predates the emergence of the modern breeds in the 19th century. Dogs with a similar appearance to the Shiba Inu were represented in dogū made during the prehistoric Jōmon period of Japanese history.
The Shiba Inu was bred to hunt and flush small game, such as birds and rabbits. Shiba lived in the mountainous areas of the Chūbu region. During the Meiji Restoration, western dog breeds were imported and crosses between these and native Japanese breeds became popular. From 1912 to 1926, almost no pure Shiba remained. From around 1928, hunters and intellectuals began to show interest in the protection of the remaining pure Shiba.
Despite efforts to preserve the breed, the Shiba nearly became extinct during World War II due to wartime food shortage, as well as outbreaks of distemper in the 1950s and 60s and the Great Tottori Fire, which discouraged preservation efforts. All subsequent dogs were bred from the only three surviving bloodlines. These bloodlines were the Shinshu Shiba from Nagano Prefecture, the Mino Shiba from the former Mino Province in the south of present-day Gifu Prefecture, and the San'in Shiba from Tottori and Shimane Prefectures.
