Understand inbreeding risk
before planning a litter.
SmartPupPro helps breeders review pedigrees, identify shared ancestors, estimate Coefficient of Inbreeding, and understand how much pedigree depth supports the calculation.
From pedigree to pairing review
COI is easier to use when it is connected to your pedigree records.
SmartPupPro helps breeders connect pedigree data, shared ancestors, genetic notes, and breeding plans in one workflow.
What is COI in dog breeding?
COI stands for Coefficient of Inbreeding. It helps estimate how closely related a breeding pair is.
COI Estimate
Review an estimated COI percentage based on the pedigree information available for the planned pairing.
Shared Ancestors
See which ancestors appear on both sides of the pedigree so relationship risk is easier to understand.
Risk Awareness
Use COI as one part of your breeding review alongside health testing, structure, temperament, and goals.
Confidence Rating
Understand whether the COI estimate is supported by deep pedigree data or limited ancestry records.
Dog breeder COI analysis tools
Review pedigree relationship risk before committing to a breeding plan.
COI Calculation
Estimate the Coefficient of Inbreeding for a potential breeding pair using available pedigree data.
- ✔ Estimated COI percentage
- ✔ Relationship review
- ✔ Breeding pair comparison
- ✔ Pairing decision support
Shared Ancestor Review
Identify common ancestors between the sire and dam so linebreeding patterns are easier to see.
- ✔ Common ancestor list
- ✔ Pedigree relationship clues
- ✔ Sire and dam comparison
- ✔ Better visibility before breeding
Pedigree Depth Rating
See how much pedigree depth was available so the COI estimate is easier to trust and explain.
- ✔ Available generations
- ✔ Data depth review
- ✔ Confidence rating
- ✔ Insufficient data notice
Breeder Decision Notes
Keep notes about why a pairing was selected, avoided, delayed, or reconsidered.
- ✔ Pairing notes
- ✔ Risk observations
- ✔ Health considerations
- ✔ Future planning history
Move beyond guessing from a printed pedigree.
SmartPupPro helps breeders estimate COI, review shared ancestors, understand pedigree depth, and connect the results to real breeding plans.
Start FreeWhy pedigree depth matters for COI.
A COI estimate is only as useful as the pedigree information behind it. A shallow pedigree may miss shared ancestors that appear farther back.

Understanding COI percentages
COI is one part of a responsible breeding decision, not the only factor.
| Estimated COI | General Interpretation | Breeder Review |
|---|---|---|
| Under 5% | Low | Often easier to justify when other health and pairing factors are favorable. |
| 5% - 10% | Moderate | Worth reviewing shared ancestors, health testing, and breeding goals carefully. |
| 10% - 15% | Elevated | May require stronger justification and a closer look at pedigree risk. |
| Above 15% | High | Should be reviewed cautiously with health, genetic, and long-term program goals in mind. |
Connect COI to real breeding decisions.
COI is most useful when it is connected to dog profiles, pedigree records, genetic results, breeder notes, and planned litters.
Plan pairings with clearer pedigree information.
SmartPupPro helps breeders estimate COI, review shared ancestors, understand pedigree confidence, and connect breeding decisions to future litter plans.
