The Golden Retriever was developed in Scotland around 1850 in order to create a specialist retriever that was capable of retrieving over rough terrain. Indigenous retrievers at the time were crossed to a tweed water spaniel (now extinct) for the original cross then to other breeds such as Irish Setters, sandy-colored Bloodhounds, the St. John's water dog of Newfoundland, and wavy-coated black retrievers. The progeny of these breedings were then inbred to set the breed type and consistency. The Golden Retriever was recognized by the American Kennel Club in 1925 and the breed was first registered in Canada in 1927. Currently Golden Retrievers fill a diverse role worldwide from seeing eye dogs to search and rescue.
One of the most prevalent issues in Golden Retrievers appears to be cancer at a young age. This is indicative of derailment of the immune system.
Golden retrievers have 3.462 effective alleles (alleles most represented) versus an overall average amount of alleles of 7.455. The overall average number of alleles indicates Golden Retriever Breeders could work to redistribute their rare alleles to maintain the diversity they still have within the breed. Analysis of Golden Retrievers shows the majority are clustered in one area genetically, however there is the presence of genetic outliers. Breeders could seek out genetic outliers to redistribute their genetic diversity. Internal relatedness (inbreeding) comparison to village dogs showed loss in diversity from village dog ancestors, however not as much as some other breeds that have been thus far investigated.

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.
