Breed Context
Outlier Index (OI) 0.37 Breed avg: 0.33
Lower contributionHigher contribution

This dog carries more mid-frequency and less-common alleles than most dogs in its breed. That makes it offer a meaningful genetic contribution to the breed, as long as it's robustly healthy and has decent function and temperament. It might have some aesthetic faults that can be improved in the next generation without losing the less common genetics it does carry. All else being equal, this dog is worth keeping in a breeding program. It is best paired with mates of relatively similar OI that are also relatively genetically unrelated. A mate that is of equal or better quality in health and structure, but complementary, will maintain the less common genetics and improve breed type.

Internal Relatedness (IR) 0.09 Breed avg: 0.02
More outbredMore inbred

This dog inherited more of the exact same DNA from each parent than is typical for the breed — a clear sign of inbreeding in its ancestry. This means it is more likely to have inherited any unknown or untested simple recessive diseases and traits, so do your testing if you didn't get clearances from its parents. If this dog has a lower OI, but is high quality, breed it, but only to an unrelated dog with equal or better health, temperament and breed type when possible. Pick puppies for your breeding program with high OI and lower IR than this dog's, and ones of equal or better quality. If this dog has a high OI, its inbreeding may actually work in the breed's favor — a more homozygous dog transmits its unusual alleles more consistently to every puppy it produces, meaning its less common genetics are less likely to be diluted in the next generation.

OI and IR are genetic diversity metrics intended to inform breeding decisions at the population level. They do not diagnose disease, predict individual health outcomes, or substitute for breed-required health testing or veterinary guidance. Conformation, temperament, longevity, and health history all belong in this decision.

The two moments breeders have influence on their breed's future are when choosing a mate, and choosing a keeper puppy. Both deserve full genetic information.
