Breeding suitability guide — Landseer
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 |
|---|---|---|---|---|
| Chondrodysplasia, SLC13A1-related | — | CARRIER | Autosomal recessive | Legacy |
| Elbow Dysplasia (ED) | Roentgen | ED-0, ED-V, or ED-1 | Polygenic | Legacy |
| Hip dysplasia (HD) | Roentgen | A, B, or C | Polygenic | HD-Curated |
| Duchenne muscular dystrophy (DMD) | DNA | CARRIER | X-linked | Legacy |
| Degenerative Myelopathy (DM) | DNA | Clear or Carrier | Autosomal recessive | HD-Curated |
| Cystinuria (Cyst-1a) | Koerperfluessigkeiten | Clear or Carrier | Autosomal recessive | HD-Curated |
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 "1" erreichen. Idealerweise besser. Phenotypen aus belasteten Linien sollten nicht für die Zucht herangezogen werden.
LegacyDuchenne muscular dystrophy (DMD)
X-chromosomal: Betroffene Rüden sollten nicht in die Zucht; tragende Hündinnen vererben das defekte Gen an 50% der Welpen.

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'
