Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Bedlington Terrier we've compiled 8 core tests (1 of them required by Klub für Terrier e.V.), drawn from breed-club regulations, the University of PEI (CIDD), and OMIA — weighted by severity and heritability.

In the Bedlington Terrier, copper toxicosis (COMMD1-associated), chronic hepatitis, and eye diseases such as cataract and retinal dysplasia are significant health risks. For breeding approval, the Klub für Terrier e.V. makes testing for copper toxicosis (COMMD1) mandatory. Responsible breeders also examine their dogs for patellar luxation (PL), ectropion / entropion, as well as skull deformities such as apple head and open fontanelle (cranioschisis). Before purchasing a puppy, ask to see the DNA status regarding copper toxicosis (COMMD1), inspect findings for chronic hepatitis proving that both parents are clear or that carriers were only mated with clear partners, and insist on clear results for cataract and PL 0.
Every breed is susceptible to certain inherited conditions. Just like humans, dogs inherit predispositions from their parents. Responsible breeders screen their breeding dogs for these conditions and make informed mating decisions to reduce the risk passed on to puppies.
No — but it's the strongest tool we have. Diet, exercise, environment, and genetics all contribute to whether a dog develops a condition. When breeders use the right tests to identify risk in potential parents, the likelihood of many conditions appearing in the puppies drops significantly.
There's no one-size-fits-all here. The core standard for the Bedlington Terrier covers 8 tests, 1 of them required by Klub für Terrier e.V.. The specific tests and passing thresholds are detailed further below.
Keep in mind
Reliable screening tests still don't exist for many hereditary conditions, and tests for complex polygenic conditions don't always predict severity in the puppies. Even so, they're a powerful tool of responsible breeding.
There are two main types of health tests:
Screen the dog's DNA for known disease-causing mutations. Can be performed from puppyhood and give a binary result (clear / carrier / affected).
Clinical and imaging exams like X-ray, ultrasound, or ophthalmoscopy. They show how a predisposition actually manifests — usually only conclusive after 12–18 months.
We group breeding programs into three levels based on testing depth. Ask your breeder directly which level they meet.
A breeder at the Great level meets the Good level; no additional tests are currently recorded for the Bedlington Terrier.
In addition to Good:
We don't currently have tests recorded at this level for the Bedlington Terrier.
These levels are a comparison framework, not an official certification. They help compare breeding programs at a glance.

Example rule — Ectropion / Entropion
Both parents must be clear or better.
We take mandatory tests from official breed regulations, build the recommended health standard from veterinary databases — and cross-check every uploaded certificate against the dog's profile using AI.
L1 = core standard: the club's required tests where its rules set them, otherwise the recommended health standard for the breed. L2 = additionally recommended or clinically indicated. L3 = lower prevalence. Every assignment carries a source and confidence rating.
VDH breeding regulations, CIDD (University of PEI), OMIA (University of Sydney), curated veterinary input.
Uploaded certificates are read by AI and checked for date, result, and consistency with the dog's profile — our team reviews anything inconclusive.
