Breeding suitability guide — American 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 Amerikanische Collies (CfAC) e.V. 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.
| Test / condition | Scoring scheme | Passing result | Inheritance | Source |
|---|---|---|---|---|
| Inflammatory Pulmonary Disease (IPD) | X-ray | clear or carrier | Autosomal recessive | — |
| Collie eye anomaly (CEA) (CEA) Club standard | — | clear or carrier | Autosomal recessive | Club für Amerikanische Collies (CfAC) e.V. |
| Progressive Retinal Atrophy, Rod-Cone Dysplasia 2 (PRA-rcd2) | DNA test | clear or carrier | Autosomal recessive | — |
| Elbow Dysplasia (ED) Club standard | X-ray | ED 0 or borderline | Polygenic | Club für Amerikanische Collies (CfAC) e.V. |
| Hip dysplasia (HD) Club standard | X-ray | HD A–B | Polygenic | Club für Amerikanische Collies (CfAC) e.V. |
| Dermatomyositis (DMS) Club standard | Skin test | result on file | Complex | Club für Amerikanische Collies (CfAC) e.V. |
| Degenerative Myelopathy (DM) Club standard | DNA test | clear or carrier | Autosomal recessive | Club für Amerikanische Collies (CfAC) e.V. |
| MDR1 gene mutation (drug sensitivity) (MDR1) Club standard | — | clear or carrier | Autosomal recessive | Club für Amerikanische Collies (CfAC) e.V. |
2. Mating rules
When one parent has a borderline result, the other parent must meet specific criteria.

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 | — |
| Merle coat pattern (M) | — | clear or carrier | Autosomal dominant | — |
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'
