Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Bohemian Shepherd we have compiled 3 mandatory and 4 recommended health tests, drawn from breed-club regulations, the University of PEI (CIDD), and OMIA — weighted by severity and heritability.
What this grade means
The Böhmischer Schäferhund is considered a robust working breed, but like many shepherd dogs, it is not free from genetic health risks. Prospective buyers should pay particular attention to hip dysplasia (HD) and elbow dysplasia (ED), as these joint issues can severely limit mobility. Additionally, degenerative myelopathy (DM) is a known concern, which is why a corresponding genetic test for the parent dogs is strongly recommended.
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. For the Bohemian Shepherd we track 3 mandatory tests plus 4 additional recommended ones. 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 are not always predictive of severity in the puppies. Even so, they're a powerful tool used by every responsible breeder.
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 performs all mandatory tests plus 4 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Progressive Retinal Atrophy (PRA)(PRA)
Augen
Progressive Retinal Atrophy (PRA) is an inherited eye disease that affects the retina, which is the light-sensitive layer of tissue at the back of the eye. In this condition, the specialized cells responsible for detecting light, known as photoreceptors, gradually degenerate and die. Because these cells cannot recover or be replaced, the disease slowly but inevitably leads to complete blindness.
Passing: CLEAR
Cataract(HC)
Augen und Sehvermögen
A cataract is a progressive clouding of the lens inside the dog's eye, which is the clear structure that focuses light onto the retina at the back of the eye. When the lens becomes cloudy or opaque, it blocks light from entering, gradually impairing the dog's vision. If left untreated, this condition can eventually lead to complete blindness in the affected eye.
Augen · Passing: Clear
MDR1 gene mutation (drug sensitivity)(MDR1)
Nervensystem
This genetic condition affects the nervous system by impairing the blood-brain barrier, which normally acts as a protective filter for the brain. Due to a missing transport protein, certain common medications can cross this barrier unchecked and accumulate in the brain. This can lead to severe, life-threatening neurological damage.
Passing: CARRIER
Pituitary hormone deficiency, LHX3-related(CPHD)
Stoffwechsel
This condition is an inherited underdevelopment of the pituitary gland, which is a small hormone-producing organ at the base of the brain. Due to a genetic mutation, the gland cannot produce enough growth hormone and other vital regulatory hormones. This deficiency severely impacts the dog's overall development and the function of other organs like the thyroid.
Passing: Clear or Carrier

We compile mandatory tests from official breed regulations and veterinary databases — and check every uploaded certificate for authenticity.
L1 = mandatory under breed-club regulations. L2 = 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 AI-extracted and reviewed by our team for authenticity, date, and result.
3 tests are currently mandatory under the relevant breed-club regulations. The most common are Elbow Dysplasia (ED), Hip dysplasia (HD), Degenerative Myelopathy (DM). Every test must be completed before mating, and the result must fall within the threshold defined by the regulation.
