Breeding suitability guide — Parson Russell Terrier
For breeders: which tests, which thresholds, which mating rules apply
1. Core standard for parents
Tests marked “Club standard” are required by Parson Russell Terrier Club Deutschland e.V. (PRTCD) - VDH/JGHV 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.

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'
