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've compiled 3 core tests (1 of them required by Klub přátel chodského psa v ČR z.s. (KPCHP)) and 4 additionally recommended tests, drawn from breed-club regulations, the University of PEI (CIDD), and OMIA — weighted by severity and heritability.

The Bohemian Shepherd (Chodsky pes) is considered a comparatively robust breed, but carries genetic risks for serious diseases such as degenerative myelopathy, hip dysplasia (HD), and elbow dysplasia (ED). The Klub přátel chodského psa v ČR z.s. (KPCHP) makes a DNA test for degenerative myelopathy mandatory for breeding approval. Responsible breeders additionally have the parent animals' joints X-rayed (HD A–C, ED 0–1) and additionally screen for eye diseases such as cataracts and progressive retinal atrophy, as well as genetic tests for the MDR1 defect (multidrug sensitivity) and pituitary dwarfism (LHX3). Ask to see the official findings for joints and degenerative myelopathy, and ensure with carriers of MDR1 or LHX3 that the mating partner is genetically clear.
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 Bohemian Shepherd covers 3 tests, 1 of them required by Klub přátel chodského psa v ČR z.s. (KPCHP), plus 4 additional recommended tests. 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 and performs 4 additional clinically recommended screenings that reduce risk in this breed.
In addition to Good:
Cataract(HC)
Augen
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.
Eye examination · Passing: clear
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
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: clear or 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

Both parents must be ED 0–1 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.
