Breeding suitability guide — Groenendael
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 |
|---|---|---|---|---|
| DNA-Identitätsnachweis | Blutprobe (DNA-Profil) | DNA-Profil / Elternschaftsnachweis erbracht | — | VDH |
| Ocular anomalies | Physisch | frei von zuchtausschließenden Augenerkrankungen | Complex | VDH |
| Elbow Dysplasia (ED) | Roentgen | ED-frei or ED-Grenzfall | Polygenic | VDH |
| Hip dysplasia (HD) | Roentgen | HD-A or HD-B | Polygenic | VDH |
| Heart disease | Physisch | frei von klinisch relevanten Herzerkrankungen | Complex | VDH |
| SELENOP-related cerebellar ataxia (CACA) | — | Clear or Carrier | Autosomal recessive | HD-Curated |
| Deafness | Hoeren | zweifelsfrei hörend (nicht taub oder einseitig hörend) | Complex | VDH |
| Wesensbeurteilung | Verhaltenstest | bestanden | — | VDH |
2. Mating rules
When one parent has a borderline result, the other parent must meet specific criteria.
Elbow Dysplasia (ED)
Polygenisch — beide Elterntiere sollten mindestens das Ergebnis "0" erreichen. Idealerweise besser. Phenotypen aus belasteten Linien sollten nicht für die Zucht herangezogen werden.
VDH3. Recommended additional tests
Sensible additions for line planning.
| Test / condition | Scoring scheme | Approved from | Inheritance | Source |
|---|---|---|---|---|
| Lumbosacral Transitional Vertebra (LTV) | Roentgen | Type 0 (free) | Complex | AI-Vet |
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'
