Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Japanese Spitz we've compiled 1 test required by Verein für Deutsche Spitze e.V. and 2 additionally recommended tests, drawn from breed-club regulations, the University of PEI (CIDD), and OMIA — weighted by severity and heritability.

In the Japanese Spitz, the focus is primarily on musculoskeletal issues, particularly patellar luxation (PL) and hip dysplasia (HD). The Verein für Deutsche Spitze e.V. mandates an examination for patellar luxation (PL) for breeding approval, allowing only dogs with grades PL 0–1 to be used for breeding. A health-conscious breeder additionally has the hips examined for hip dysplasia (HD). Before buying a puppy, ask to see the official test results of both parents to minimize the risk of joint diseases in your dog.
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 Japanese Spitz, Verein für Deutsche Spitze e.V. requires 1 test for breeding approval, plus 2 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 2 additional clinically recommended screenings that reduce risk in this breed.
In addition to Good:
Progressive Retinal Atrophy, rod-cone dysplasia 4(PRA-rcd4)
Augen
Progressive Retinal Atrophy (rcd4) is an inherited eye disease that causes the gradual degeneration of the retina, which is the light-sensitive layer at the back of the eye. Over time, the specialized photoreceptor cells responsible for detecting light and color slowly die off. This progressive loss of cells eventually leads to complete blindness in both eyes.
DNA test · Passing: clear or carrier (carriers only with a clear partner)
Hip dysplasia(HD)
Bewegungsapparat
Hip dysplasia is an inherited skeletal disorder where the ball and socket of the hip joint do not fit together properly. Instead of sliding smoothly, the bones rub and grind against each other, wearing down the protective cartilage. Over time, this chronic friction causes joint instability, painful inflammation, and progressive arthritis, which is the gradual wear and tear of the joint.
X-ray · Passing: Keine mittlere oder schwere HD (leichte HD oder Übergangsform nur mit HD-freiem Partner)
Not health tests, but required for breeding: the club asks for these results too. They don't count toward the risks or the rating.

Example rule — Patellar Luxation
Both parents must be PL 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.
