Breeding suitability guide — American Bulldog
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) | Roentgen | FCI 0 or OFA Normal | Polygenic | Legacy |
| Hip dysplasia (HD) | Roentgen | FCI A or B, OFA Fair or better, or PennHIP DI ≤ 0.50 | Polygenic | CIDD |
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.
Legacy3. Recommended additional tests
Sensible additions for line planning.
| Test / condition | Scoring scheme | Approved from | Inheritance | Source |
|---|---|---|---|---|
| Hyperuricosuria (HUU) | Koerperfluessigkeiten | Clear or Carrier | Autosomal recessive | AI-Vet |
| Lysosomal storage diseases (LSD) | DNA | CLEAR | Autosomal recessive | 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'
