Breeding suitability guide — Collie (Shorthair)
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 |
|---|---|---|---|---|
| Collie eye anomaly (CEA) (CEA) | — | Clear or Carrier | Autosomal recessive | AI-Vet |
| Progressive Retinal Atrophy, Rod-Cone Dysplasia 2 (PRA-rcd2) | DNA | Clear or Carrier | Autosomal recessive | AI-Vet |
| Dermatomyositis (DMS) | Haut | Clear or Carrier | Complex | AI-Vet |
| MDR1 gene mutation (drug sensitivity) (MDR1) | — | Clear or Carrier | Autosomal recessive | AI-Vet |
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 |
|---|---|---|---|---|
| Canine cyclic hematopoiesis (GCS) | DNA | CARRIER | Autosomal recessive | AI-Vet |
| Hip dysplasia (HD) | Roentgen | C or better | 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 check each upload for authenticity — the profile tile then shows 'verified'
