Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Hovawart we have compiled 2 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 Hovawart is considered a robust and exceptionally healthy breed, with hereditary conditions effectively managed through strict breeding regulations. Nevertheless, prospective buyers should remain mindful of hip dysplasia (HD), which remains a concern despite successful breeding programs, as well as the neurological condition degenerative myelopathy (DM). Hypothyroidism also occurs occasionally in the breed, so it is advisable to check that the parent dogs have undergone the appropriate health screenings.
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 Hovawart we track 2 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:
Ocular anomalies
Augen
Ocular anomalies are a group of congenital malformations, meaning they are present from birth, that affect various structures of the dog's eye such as the retina, lens, or cornea. These developmental defects alter the normal structure of the visual system, potentially impacting how light is focused or how the eye functions. The condition is complex and can range from minor physical irregularities to severe structural changes.
Physisch · Passing: Free of hereditary eye diseases
Heart disease
Herz
Heart disease refers to structural or functional abnormalities of the heart muscle, valves, or electrical system that impair its ability to pump blood effectively. This reduced pumping efficiency prevents the cardiovascular system from delivering adequate oxygen and nutrients to the body's tissues. Some forms are congenital, meaning present from birth, while others are acquired over time due to wear or genetic factors.
Physisch · Passing: No signs of hereditary heart disease
Degenerative Myelopathy(DM)
Nervensystem
Degenerative Myelopathy is a progressive disease of the spinal cord where the protective sheath around the nerves slowly breaks down. This deterioration disrupts the vital communication signals between the brain and the muscles of the hind limbs. Over time, this lack of signal transmission leads to a complete loss of muscle control in the back legs.
DNA · Passing: Clear or Carrier
Primary hypothyroidism
Stoffwechsel
Primary hypothyroidism is an endocrine disorder where the thyroid gland, located in the neck, fails to produce enough thyroid hormones. This hormone deficiency is usually caused by the immune system mistakenly attacking the gland or by the gradual replacement of thyroid tissue with fat. Because these hormones regulate how the body uses energy, a shortage slows down the dog's entire metabolism.
Passing: Normal thyroid values

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