Breeding suitability guide — Brussels Griffon
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 |
|---|---|---|---|---|
| Patellar Luxation (PL) | Physisch | Grad 0 | Polygenic | Legacy |
2. Mating rules
When one parent has a borderline result, the other parent must meet specific criteria.
Patellar Luxation (PL)
Polygenisch — beide Elterntiere sollten mindestens das Ergebnis "0" erreichen. Idealerweise besser. Phenotypen aus belasteten Linien sollten nicht für die Zucht herangezogen werden.
Legacy3. Recommended additional tests
Sensible additions for line planning.
| Test / condition | Scoring scheme | Approved from | Inheritance | Source |
|---|---|---|---|---|
| Progressive Retinal Atrophy (PRA) (PRA) | — | CARRIER | Autosomal recessive | CIDD |
| Cataract (HC) | Augen | CLEAR | Complex | CIDD |
| Chiari-like malformation (CM) and syringomyelia (SM) (CM/SM) | Roentgen | A | Complex | CIDD |
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 check each upload for authenticity — the profile tile then shows 'verified'
