Breeding suitability guide — Giant Schnauzer
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 | Physisch | Vorläufig frei / Clinically unaffected | Complex | Legacy |
| Hip dysplasia (HD) | Roentgen | HD-A or HD-B | Polygenic | Legacy |
| Hyperuricosuria (HUU) | Koerperfluessigkeiten | Clear or Carrier | Autosomal recessive | Legacy |
| Primary hypothyroidism | — | Normal | Complex | HD-Curated |
2. Mating rules
When one parent has a borderline result, the other parent must meet specific criteria.
Ocular anomalies
Polygenisch — beide Elterntiere sollten mindestens das Ergebnis "CLEAR" erreichen. Idealerweise besser. Phenotypen aus belasteten Linien sollten nicht für die Zucht herangezogen werden.
LegacyHip dysplasia (HD)
Polygenisch — beide Elterntiere sollten mindestens das Ergebnis "B" erreichen. Idealerweise besser. Phenotypen aus belasteten Linien sollten nicht für die Zucht herangezogen werden.
LegacyHyperuricosuria (HUU)
Autosomal rezessiv: Zwei Träger (CARRIER) dürfen nicht miteinander verpaart werden — 25% der Welpen wären betroffen. Betroffene Hunde sollten gar nicht in der 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 check each upload for authenticity — the profile tile then shows 'verified'
