Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Hamiltonstövare we have compiled 1 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 Hamiltonstövare is considered a robust Swedish hunting breed, though our database does not currently list any specific mandatory health tests for it. Nevertheless, prospective buyers should look out for hip dysplasia (HD) and epilepsy, as these conditions can occur within the breed. Additionally, eye conditions such as ectropion should be ruled out by a veterinarian in the parent dogs before purchase.
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 Hamiltonstövare we track 1 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:
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: Frei
Elbow Dysplasia(ED)
Bewegungsapparat
Elbow dysplasia is a developmental disorder of the musculoskeletal system where the three bones forming the elbow joint do not fit together properly. This misalignment causes abnormal friction and wear on the joint cartilage, eventually leading to painful, chronic joint inflammation and arthritis. It is a complex genetic condition influenced by multiple genes.
Roentgen · Passing: 0 (Frei)
Cerebellar Ataxia(CA1)
Nervensystem
Cerebellar Ataxia is an inherited neurological disorder that affects the cerebellum, which is the part of the brain responsible for coordinating movement and balance. Due to an autosomal-recessive genetic mutation, nerve cells in this brain region progressively degenerate. This gradual loss of cells prevents the brain from properly controlling the body's movements.
DNA · Passing: Träger oder frei
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.

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