Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Westphalian Dachsbracke we have compiled 2 mandatory and 7 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 Westfälische Dachsbracke receives a grade of C, as it carries an above-average genetic burden with 10 recorded mandatory health tests. Prospective buyers should pay close attention to breeding tests for epilepsy as well as eye conditions such as ectropion and entropion. Even though the breed is considered a traditional hunting dog, careful selection of the parent animals is essential due to these risks.
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 Westphalian Dachsbracke we track 2 mandatory tests plus 7 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 7 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Cleft palate
Allgemeine Fitness und Anatomie
A cleft palate is a congenital birth defect where the roof of the mouth fails to fuse properly during development in the womb. This failure leaves an abnormal opening between the oral cavity and the nasal passages. Because these two systems are directly connected, food, liquids, and air cannot be properly separated during swallowing.
Physisch · Passing: CLEAR
Dental abnormalities
Andere
Dental abnormalities refer to congenital or acquired malformations of the teeth and jaw structure, affecting the skeletal and digestive systems of the mouth. This includes malocclusions, which are misalignments where the upper and lower teeth do not meet properly, as well as missing or extra teeth. These structural issues can interfere with normal chewing and cause teeth to rub painfully against the sensitive tissues of the mouth.
Passing: CARRIER
Ectropion / Entropion
Augen
These are structural eyelid abnormalities affecting a dog's eyes. In cases of entropion, the eyelid rolls inward, causing the eyelashes or fur to rub painfully against the surface of the eyeball. In ectropion, the eyelid sags or rolls outward, leaving the sensitive inner lining of the eye exposed and unprotected.
Passing: CLEAR
Congenital blindness
Augen und Sehvermögen
Congenital blindness is a severe or complete loss of vision present from birth, affecting the eyes and the neural pathways connected to the brain. It is caused by developmental abnormalities in key structures like the retina, which is the light-sensitive tissue at the back of the eye, or the optic nerve. These structural defects prevent visual signals from being properly formed or transmitted.
Physisch · Passing: CLEAR
Dermatosis
Haut und Fell
Dermatosis is a general term for any disease or abnormal condition affecting a dog's skin, which is the body's largest organ system. These conditions disrupt the skin's natural protective barrier, structure, or pigment, often due to a complex mix of genetic and environmental factors. Because it is an umbrella term, it covers various specific skin disorders rather than a single disease.
Passing: no skin problems
Congenital deafness(CHSD)
Nervensystem
Congenital deafness is a hereditary hearing loss present from birth that affects the inner ear's sensory cells, preventing sound signals from reaching the brain. It is often linked to specific genetic variants, such as those associated with certain coat patterns like merle or piebald, or breed-specific conditions like Early Onset Adult Deafness (EOAD). This genetic defect causes the vital blood supply to the inner ear to fail, leading to the permanent degeneration of the hearing nerve cells.
Physisch · Passing: BILATERAL_HEARING
Epilepsy(IE)
Nervensystem
Epilepsy is a chronic disorder of the brain and nervous system where abnormal electrical activity causes sudden, temporary disruptions in normal brain function. These disruptions lead to repeated seizures, which are involuntary changes in body movement, sensation, or behavior. Because the underlying cause is often complex, the brain's electrical signaling remains permanently prone to these sudden misfires.
Physisch · Passing: no epilepsy

2 tests are currently mandatory under the relevant breed-club regulations. The most common are DNA-Identitätsnachweis, Hip dysplasia (HD). Every test must be completed before mating, and the result must fall within the threshold defined by the regulation.
