Breeding suitability guide — Smooth Collie
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.

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 | Passing result | Inheritance | Source |
|---|---|---|---|---|
| Canine cyclic hematopoiesis (GCS) | DNA test | clear or carrier | Autosomal recessive | AI-Vet |
| Hip dysplasia (HD) | X-ray | HD A–C | Polygenic | 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 extract the results from each upload using AI and check them for consistency with the dog's profile — the profile tile then shows 'verified'
