Health & standard
framework
Our breeding framework is guided by long-term functional health, native temperament, and responsible preservation of the Shiba Inu as a Japanese breed. Rather than focusing on short-term outcomes or checklists alone, we prioritize maturity, stability, and lived evaluation over time. This approach allows us to make thoughtful breeding decisions that support the well-being of both individual dogs and the breed as a whole.
What we mean by Health
When we talk about health, we are not referring simply to the absence of disease. Health, to us, is the ability of a dog to live well — physically, mentally, and socially — over its entire lifetime. A healthy Shiba Inu should move efficiently, recover well from activity, maintain emotional stability, and adapt to daily life without chronic stress. These qualities cannot be measured at a single moment. They are revealed through time, environment, and careful observation.
Our goal is not to produce dogs that merely pass health checks, but dogs that remain sound, balanced, and resilient as they mature.
Genetic screening and veterinary testing are important tools, and we use them responsibly (check our health tests below). However, health cannot be reduced to a checklist.
Functional health includes structure that supports efficient movement, endurance that allows a dog to stay active without breakdown, and recovery that reflects physical robustness. Many of these qualities only become clear as a dog matures and lives an active, structured life.
For this reason, we allow our dogs to fully mature before entering any breeding program. Time is an essential part of evaluation — not a delay, but a safeguard.

temperament is health
Temperament is not separate from health; it is one of its foundations.
The Shiba Inu is a native Japanese breed developed to live and learn within a canine group. Its temperament is shaped by social structure, clear boundaries, and responsibility — not by constant human management or enforced obedience alone.
Our kennel environment reflects this origin. Dogs are raised in a socially structured, highly interactive setting where they learn appropriate communication, self-regulation, and confidence through lived experience with both people and other dogs.
Before breeding, each dog must demonstrate emotional stability, clarity of boundaries, and the ability to interact appropriately within the group. Dogs that show natural leadership, mentorship, and calm authority play an important role in guiding younger dogs, contributing to a stable social environment.
This approach supports the development of a Shiba Inu temperament that is thoughtful, confident, and resilient — traits that are essential for lifelong well-being and successful integration into family life.
standards shape outcomes
Breed standards do more than describe appearance. They influence breeding priorities, selection decisions, and the long-term direction of a population.
What a standard allows or requires sends a signal to breeders. Over time, these signals shape structure, temperament, and functional health across generations. Small allowances may seem inconsequential in individual dogs, but their effects accumulate at the population level. Understanding this long-term impact is essential to ethical, preservation-focused breeding.
Comparing standards:
Afunctional perspective
Breed standards vary in purpose and structure. Below is a functional comparison between the Nihon Ken Hozonkai (NIPPO) standard and the Canadian Kennel Club (CKC) standard for the Shiba Inu.
This comparison is provided to explain our breeding framework and decision-making process — not to rank or discredit registries. Original source documents are provided for transparency and independent reference.
The Shiba Inu is widely regarded as one of the healthiest dog breeds, with few health issues typically seen in youth. A well-managed lifestyle can also help reduce the risk of age-related conditions. However, following near extinction after World War II, efforts to restore the breed involved a limited gene pool and some degree of inbreeding. While these breeding programs successfully preserved the Shiba Inu, certain hereditary health concerns today can be traced back to that period.
The goal of preserving this breed is to select against the unintended or harmful mixing of genes out of this native breed. We strictly aligned with the standard published by NIPPO to ensure the health and genetic stability of this breed.
Below are key health considerations every prospective owner should be informed about:

Shiba Inu can be prone to several eye conditions due to its inbreeding history. One of the most common is distichiasis, where extra eyelashes grow abnormally, potentially irritating the eye. Persistent pupillary membranes and entropion, where the eyelids roll inward, are also seen in puppies. More serious conditions include cataracts, which can develop as early as two years of age and may lead to blindness, and glaucoma, which requires early diagnosis and treatment to prevent vision loss. While progressive retinal atrophy (PRA) is rare in Shiba Inu, it is a known concern in some lines.
What we can do as a breeder:
- Up-to-Date OFA eye test
- genetic testing panels: Degenerative Myelopathy; Progressive Retinal Atrophy; Primary Lens Luxation (PLL)
Like many small breeds, the Shiba Inu is susceptible to dental issues such as misaligned teeth, gingivitis, and early tooth loss. Genetic factors can also contribute to overbites, underbites, and missing teeth. However, as a native and one of the ancient breed, Shibas are expected to have a full and functional bite in accordance with breed standards. After decades of efforts to preserve genetic diversity, NIPPO now strictly requires all dogs to have a full set of 42 well-developed teeth and a correct, functional bite, while the 2025 new CKC standard allows 5 missing teeth to be shown, changing from 4 missing teeth in the 2006 version.
What breeders can do:
-
Unfortunately, there is currently no genetic test panel specifically for dental occlusion. However, bite alignment/missing teeth is a visible trait that can be evaluated by eye.
-
Breeders should be able to demonstrate the full dentition and bite alignment of both parental dogs for at least 3 generations.
-
If any teeth are missing, breeders should disclose whether the loss was due to physical trauma rather than genetic causes, and provide relevant history if available.
Shiba Inu may experience food and inhalant allergies, which can cause symptoms like itchy skin, hair loss, and runny eyes. Pollen and dust mites are common triggers. Additionally, hypothyroidism, an autoimmune disorder, is seen in the breed and can lead to weight gain, lethargy, and coat issues if left untreated. Regular veterinary check-ups and a well-balanced diet can help manage these conditions.
What we can do as a breeder:
- unfortunately, there aren't any genetic testing panel in term of autoimmune disorders. No definitive DNA test yet for Shibas, but thyroid function panels (T4, TSH, TgAA) are recommended to monitor breeding dogs.
- breeder need to excluding any potential individuals from the lineage. i.g: monitoring population, excluding any individuals who have allergy reactions in the past.
- keep a record of at least 3 generation regarding any autoimmune conditions including aging population.
Despite their small size, Shiba Inu can suffer from hip dysplasia, an inherited condition affecting the hip joint’s development. Patellar luxation is another common orthopedic issue seen in Shiba Inus. These conditions can lead to discomfort and mobility problems, making it essential to choose puppies from parents screened for orthopedic health.
What we can do as a breeder:
- Provide each parental dog with full physical examinations periodically, which helps track changes in condition over age.
- radiographic screening method for evaluation when periodical exams show abnormalities or a change in the situation.
A rare but serious genetic condition in Shiba Inu is GM1 gangliosidosis, a neurological disorder caused by a recessive gene mutation. Affected puppies may develop symptoms such as vision loss, difficulty walking, head tremors, and lethargy, typically appearing between 5 to 6 months of age. DNA testing of breeding dogs helps prevent this condition from being passed on.
What we can do as a breeder:
- Shiba Inu specific GM1 gangliosidosis is a testable disorder, which can be completed with genetic laboratory.
- genetic test should be test for GM1 gangliosidosis scanning.
In Shibas, the ideal urajiro pattern includes white or cream on the cheeks, under the jaw, throat, chest, inside of the ears, belly, and underside of the tail and legs. A reverse mask/pigmentation fault occurs when the white urajiro expands too far, particularly overtaking the muzzle and eyes, removing the desired dark facial expression. It can create a “white face” look even in puppies — sometimes giving them an older or faded appearance. The pigmentation fault is NOT in the pathological sense but can be related to multiple genes, possibly including: Agouti (A locus): Affects base coat color (e.g., red, sesame, black and tan); Modifier genes: These can cause variations in how dark or pale facial markings appear; and KIT or MC1R (though more studied in other breeds): Possibly involved in the distribution of white markings. If the depigmentation progresses with age or is accompanied by skin changes, lesions, or nasal/eye rim depigmentation, it could indicate: Vitiligo, Autoimmune disease (like DLE), Nutritional or thyroid issues.
What breeders can do:
-
This is not a pathological issue.
-
But to prevent further risk, breeders should be aware of parental dogs in terms of aging appearances at least 3 generations.
-
If a white face happens before 4 years of age, breeders should exclude the dog from showing and breeding plans (which is allowed under 2025 Standard ).
Breeding a Healthy Puppy
When selecting a Shiba Inu puppy, ensure the breeder follows proper pregnancy management, limiting the dam to one litter per year and providing high-quality care, pre-pregnancy checkup, endocrinology test, and pre/in-pregnancy ultrasound. Puppies should be raised in a clean environment, receive early house training, socialization, and undergo veterinary health checks before adoption. Request health clearances for common genetic conditions, and confirm the breeder’s commitment to health testing.
Given the breed's historical bottleneck following World War II, maintaining a well-documented pedigree—ideally spanning five or more generations—is essential for tracking inherited traits and making informed breeding decisions. Responsible breeding practices not only minimize hereditary disorders but also help preserve the breed’s natural structure, temperament, and overall health.
Best practices for breeders:
-
Incorporate the coefficient of inbreeding (COI) into line-breeding plans to monitor genetic closeness.
-
Utilize genetic diversity testing to guide pairing decisions and maintain a healthy gene pool.
-
Support sustainable genetic advancement by preserving an effective population structure—specifically, by maintaining a broader representation of sires (males) than typically seen in most closed breeding populations.
