2. Mating rules
When one parent has a borderline result, the other parent must meet specific criteria.
We currently have no structured mating rules for this breed. Please consult your club's regulation.
3. Recommended additional tests
Sensible additions for line planning.
| Test / condition | Scoring scheme | Approved from | Inheritance | Source |
|---|---|---|---|---|
| Progressive Retinal Atrophy (PRA) (PRA) | — | CLEAR | Autosomal recessive | AI-Vet |
| Lens luxation (PLL) | Eye examination | Clear or Carrier | Autosomal recessive | 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 AI-extract each upload and check it for consistency with the dog's profile — the profile tile then shows 'verified'
