Health Testing Guide
Which tests matter, how to spot responsible breeders — and what it costs when things go wrong.
For the Bouvier des Flandres we've compiled 3 tests in the recommended health standard and 5 additionally recommended tests, drawn from veterinary databases such as CIDD (University of PEI) and OMIA — weighted by severity and heritability.

In the Bouvier des Flandres, there are breed-typical risks for hip dysplasia (HD) and elbow dysplasia (ED), as well as for severe diseases such as aortic stenosis or laryngeal paralysis. A responsible breeder therefore has their breeding dogs comprehensively examined for joints and eyes, as well as cardiologically. When buying a puppy, make sure that the parents are proven to have hip dysplasia (HD) with HD A–B and elbow dysplasia (ED) with ED 0–1. Also ask to see written reports confirming that both parents are free of cataract and primary open-angle glaucoma, and have an unremarkable examination for aortic stenosis.
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 recommended health standard for the Bouvier des Flandres covers 3 tests, plus 5 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 5 additional clinically recommended screenings that reduce risk in this breed.
In addition to Good:
Megaesophagus(ME)
Andere
Megaesophagus is a disorder of the digestive system where the esophagus, the muscular tube connecting the throat to the stomach, becomes abnormally stretched and loses its muscle tone. Because these muscles can no longer contract to push food and liquid downward, meals become trapped in the tube. This trapped material is typically regurgitated, meaning it is passively cast back up before ever reaching the stomach.
X-ray
Laryngeal Paralysis(LP)
Atmung
Laryngeal paralysis is a respiratory disorder where the nerves controlling the muscles of the larynx, or voice box, fail to function properly. This failure prevents the vocal folds from opening when the dog inhales, which severely restricts airflow into the windpipe and lungs. Over time, this lack of proper movement can lead to significant breathing difficulties.
X-ray
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
Primary Open-Angle Glaucoma(POAG)
Augen
Primary open-angle glaucoma is an inherited eye disease where the natural fluid inside the eye cannot drain properly. This fluid buildup causes a gradual increase in pressure within the eyeball, which eventually damages the optic nerve, the connection between the eye and the brain. Without management, this pressure leads to permanent blindness.
Eye examination · Passing: clear
Aortic valve stenosis(AS)
Herz
Aortic stenosis is a narrowing of the aortic valve in the heart, which controls blood flow from the main pumping chamber (the left ventricle) to the rest of the body. Because of this restriction, the heart muscle must work much harder to pump blood, which eventually causes the muscle wall to thicken abnormally. This is a severe cardiovascular condition that can strain the heart over time.
Passing: normal

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.

Uploaded certificates are read by AI and checked for date, result, and consistency with the dog's profile — our team reviews anything inconclusive.
