Breeding suitability guide — Great Pyrenees
For breeders: which tests, which thresholds, which mating rules apply
1. Mandatory tests for parents
These tests must be on file for every breeding animal.
| Test / condition | Scoring scheme | Approved from | Inheritance | Source |
|---|---|---|---|---|
| Ocular anomalies | Physical examination | clear | Complex | Legacy |
| Elbow Dysplasia (ED) | X-ray | ED 0 | Polygenic | Legacy |
| Hip dysplasia (HD) | X-ray | HD A–B | Polygenic | CIDD |
| Patellar Luxation (PL) | Physical examination | PL 0 | Polygenic | Legacy |
2. Mating rules
When one parent has a borderline result, the other parent must meet specific criteria.
Ocular anomalies
Polygenisch — beide Elterntiere sollten das Ergebnis „frei“ erreichen. Tiere aus belasteten Linien sollten nicht für die Zucht eingesetzt werden.
LegacyElbow Dysplasia (ED)
Polygenisch — beide Elterntiere sollten das Ergebnis „ED 0“ erreichen. Tiere aus belasteten Linien sollten nicht für die Zucht eingesetzt werden.
LegacyPatellar Luxation (PL)
Polygenisch — beide Elterntiere sollten das Ergebnis „PL 0“ erreichen. Tiere aus belasteten Linien sollten nicht für die Zucht eingesetzt werden.

4. HonestDog verification
- Upload a legible certificate (PDF or photo) per test in the breeder dashboard
- Certificate must show date, examining vet, and FCI/VDH logo
- Certificates older than 36 months are flagged as stale
- We AI-extract each upload and check it for consistency with the dog's profile — the profile tile then shows 'verified'
