The public treats "inbreeding" as a moral verdict. The science treats it as risk management, measured by a specific tool called the Coefficient of Inbreeding (COI). Every established dog breed in existence was created by deliberately using related dogs to stabilize type and temperament. Lineage concentration is historically normal. It is how breeds are made.
This page addresses the hard questions directly. Not because the answers are easy — but because transparency is the only durable answer to skepticism. A program that hides its lineage practices invites suspicion. A program that explains them plainly, cites the science, and demonstrates a responsible framework invites trust.
The Questions That Will Come — Answered Directly
The COI — What It Measures and What It Means
The Coefficient of Inbreeding expresses the probability that two copies of any given gene are identical by descent — both copies tracing back to the same ancestor. Higher COI means more homozygosity. This is what "setting type" means genetically: traits become consistent because variation has been reduced.
The EU Platform on Animal Welfare recommends keeping combined COI below 6.5%. The Institute of Canine Biology suggests ~5% as a working target for healthy diversity.
What High COI Risks
These are the documented risks of high COI — stated plainly because honest disclosure is part of responsible practice:
Inbreeding Depression
Reduced fertility, smaller litters, lower survival rates.
Immune Compromise
Genetic diversity supports immune function. Close breeding reduces it.
Recessive Disease
High COI increases probability that recessive disease alleles are expressed.
Orthopedic Issues
Hip dysplasia and similar conditions have genetic components that concentrate.
These risks are real. They are why COI management, health testing, and a step-down outcrossing plan are not optional — they are the ethical infrastructure that makes lineage concentration defensible.
Every Breed Was Made This Way
This is not contested. Every recognized purebred dog breed began with a founder or small founder group whose traits were concentrated through deliberate close breeding.
- → German Shepherd — developed by Max von Stephanitz from a small group of working shepherd dogs
- → Border Collie — traces heavily to a single founding sire named Old Hemp
- → Labrador Retriever — traces to a small group of St. John's Water Dogs from Newfoundland
- → Chinook — the entire breed traces to a single founding sire also named "Chinook"
Close breeding to "set" type is the historical mechanism of breed development. It is not aberrant. What is different now is that we have tools those founders lacked — COI calculation, DNA-based genetic screening, population genetics research. We can practice the same concentration more responsibly than they ever could.
The No-Culling Distinction
The history of dog breed development includes culling — removing dogs that did not meet the desired criteria. This practice still occurs in some working-dog programs today. It is not discussed openly. But it is the historical norm.
We Do Not Cull. Ever.
Every dog born into this line is placed — into a loving home, with a guardian who understands the lineage. Dogs that do not contribute to the breeding core are companions, not casualties. The process takes longer because of this. We believe that is the right way to do it.
This is a genuine ethical differentiator from the historical norm — and from current practice in some programs. It is stated here as policy, not aspiration.
The Responsible Concentration Framework
Lineage concentration is defensible when it operates within a clear framework. Ours:
Calculate and publish COI
Use pedigree analysis tools before each breeding. Publish the numbers on the site. Explain what they mean in plain language.
Stay within recognized thresholds
Target below the EU guideline of 6.5% combined COI where possible. When a pairing exceeds it, state why and what monitoring accompanies it.
Health test every breeding animal
Baseline screens before any pairing. Publish results. No hidden information about the health of the breeding animals.
Plan the step-down
Outcrossing will be introduced in future generations to restore genetic diversity. This is the difference between managed concentration and careless repetition.
No culling — placement for every dog
Non-negotiable. Every dog born into the line receives a home, a guardian, and a blessing scroll.
Health and temperament over appearance
The goal is Rocky's character. A healthy, sound, well-tempered dog is a success regardless of phenotype. We do not cull for appearance.

Lead with honesty: "We practice lineage concentration. We know what that means, we know what the risks are, and we have chosen to do it responsibly — because the preservation work is worth doing, and because doing it honestly is the only way it is worth doing."
The no-culling point is the ethical differentiator. State it plainly and early. It distinguishes this program from most of dog breeding history.
