Breeding suitability guide — Cardigan Welsh Corgi
For breeders: which tests, which thresholds, which mating rules apply
1. Core standard for parents
Tests marked “Club standard” are required by Club für Britische Hütehunde e.V. (CfBrH) for breeding approval — they must be on file for every breeding animal. The others are part of the recommended health standard and should be on file as well.

When one parent has a borderline result, the other parent must meet specific criteria.
Hip dysplasia (HD)
See the mating rule in your club's regulation.
3. Recommended additional tests
Sensible additions for line planning.
| Test / condition | Scoring scheme | Passing result | Inheritance | Source |
|---|---|---|---|---|
| Lens luxation (PLL) | Eye examination | clear | Autosomal recessive | CIDD (Univ. PEI) |
| Persistent pupillary membranes (PPM) (PPM) | Eye examination | clear | Unknown | CIDD (Univ. PEI) |

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'
