Breeding suitability guide — Newfoundland
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 |
|---|---|---|---|---|
| Elbow Dysplasia (ED) | X-ray | ED 0–1 | Polygenic | Legacy |
| Hip dysplasia (HD) | X-ray | HD A–C | Polygenic | CIDD |
| Aortic valve stenosis (AS) | — | normal | Complex | CIDD |
| Heart disease | Physical examination | normal | Complex | Legacy |
| Cystinuria (Cyst-1a) | Body-fluid analysis | clear or carrier | Autosomal recessive | Legacy |
2. Mating rules
When one parent has a borderline result, the other parent must meet specific criteria.
Elbow Dysplasia (ED)
Polygenisch — beide Elterntiere sollten das Ergebnis „ED 0–1“ erreichen. Tiere aus belasteten Linien sollten nicht für die Zucht eingesetzt werden.
LegacyHeart disease
Polygenisch — beide Elterntiere sollten das Ergebnis „unauffällig“ erreichen. Tiere aus belasteten Linien sollten nicht für die Zucht eingesetzt werden.
LegacyCystinuria (Cyst-1a)
Autosomal rezessiv: Zwei Träger 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 extract the results from each upload using AI and check them for consistency with the dog's profile — the profile tile then shows 'verified'
