2. Mating rules
When one parent has a borderline result, the other parent must meet specific criteria.

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'
