The Akita traces its roots to the mountainous Akita prefecture of northern Japan, where spitz-type hunting and guarding dogs had existed for centuries. By the early 20th century the native Japanese dogs had been crossed extensively with imported Western breeds - Mastiff, German Shepherd, and others - producing a larger, more varied dog. After World War II, American servicemen brought these dogs back to the United States and developed them along their own lines, preserving the heavier Western-influenced type. In parallel, Japanese breeders pulled their population back toward the older native type, which became the Japanese Akita (Akita Inu). The two lines have been genetically separate for decades and are recognized as distinct breeds by the FCI and many registries, though the AKC continues to treat them as one breed. The American Akita is the larger, bulkier dog with a broader color range, reflecting its post-war American development.

Hip and elbow dysplasia, progressive retinal atrophy, hypothyroidism, and autoimmune conditions including sebaceous adenitis and autoimmune thyroiditis are the main concerns. Gastric dilatation-volvulus (bloat) is a significant risk given the deep chest. Akitas as a group are sensitive to certain drugs and anesthetics, and breeders should be aware of VKH-like uveodermatologic syndrome, which affects this breed at elevated rates.
VGL has reported American Akitas carrying an average of around 6.73 alleles across the 33 STR loci, with an effective allele count near 2.96. The gap between average and effective alleles is typical - a subset of common alleles dominates, and the rarer ones are the ones that need deliberate protection through breeding decisions. VGL testing has found American Akitas with observed heterozygosity close to expected, giving an inbreeding coefficient near zero. That is a reasonably good signal at the breed-wide level, though individual IR values still vary. The breed's split from the Japanese Akita and its post-war American development from a relatively narrow base mean breeders should stay attentive to maintaining diversity rather than assuming the current balance is self-sustaining.

The Dog Leukocyte Antigen (DLA) region controls immune function and is the most polymorphic portion of the canine genome. Every dog carries two sets of DLA haplotypes — one from each parent — which almost never recombine across generations. Frequency percentages reflect how often each haplotype appears across all allele copies in the breed, not the percentage of dogs carrying it.

The Canine Diversity Test from UC Davis Veterinary Genetics Laboratory is the foundation of BetterBred’s breed management tools. Testing your dog adds to the breed database and gives you access to the full suite of breeding analysis tools.

OI
Outlier Index

The Outlier Index (OI) measures how unusual a dog’s allele combination is relative to the tested population of its breed. A higher OI means the dog carries alleles at lower frequencies across the breed — genetic variants that are underrepresented in the population as a whole.

Dogs with high OI are genetically valuable because they carry diversity that most other tested dogs don’t share. Breeding them thoughtfully into the broader population helps redistribute lower-frequency alleles rather than allowing them to become even rarer over generations.

The breed average shown here reflects all dogs tested in the BetterBred database. The senior and youngster comparisons show whether diversity is trending up or down in recent generations.
AGR
Average Genetic Relatedness

Average Genetic Relatedness (AGR) measures how similar a dog’s DNA is, on average, to every other tested dog in the breed. It reflects the dog’s mean kinship — how closely related it is to the population as a whole.

A lower AGR means the dog is more genetically distinct from the majority of the breed. Dogs with low AGR carry alleles at lower frequencies across the tested population, making them higher-priority candidates for inclusion in a well-managed breeding program.

AGR is conceptually related to mean kinship used in conservation genetics for managed species populations. A declining AGR average in younger dogs suggests the breed is successfully redistributing genetic diversity across generations.
IR
Internal Relatedness

Internal Relatedness (IR) measures how much identical genetic material an individual dog inherited from both parents. IR is a useful indicator of inbreeding: lower IR generally reflects lower inbreeding, and it is widely used and reported in the scientific literature.

A high IR is not the cause for alarm it might appear. Elevated IR can often be resolved in a single generation by pairing with a dog whose ancestry is less represented in the breed. It is a signpost, not a sentence.

BetterBred reports IR for reference, but it is not our primary breeding guidance tool. OI and AGR together give a more complete and actionable picture of a dog’s genetic value to the population.

AGR tells you which dogs are genetically unusual relative to the population. OI tells you which dogs are most valuable to preserve. OI specifically weights mid-frequency alleles, identifying dogs whose ancestry is underrepresented in a way most likely to benefit the breed.
