Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Miniature Pinscher we have compiled 2 mandatory and 6 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 Zwergpinscher is rated with a B grade, as it shows an average health burden that can be well managed through standard screenings. The main focus here is on patellar luxation (kneecap dislocation) as well as hereditary eye conditions, for which mandatory health tests are required before breeding. If you ensure that the parents are healthy and have clear test results, you will gain an agile and essentially robust companion.
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 Miniature Pinscher we track 2 mandatory tests plus 6 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 6 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Disorders of sexual development - sex reversal(DSD)
Andere
This is a congenital condition affecting the reproductive system where a dog's genetic sex (their chromosomes) does not match their physical gonads (internal reproductive organs like ovaries or testes) or external genitalia. This mismatch occurs during early development in the womb. Because it is inherited in an autosomal recessive pattern, a puppy must inherit the mutated gene from both parents to be affected.
DNA · Passing: CARRIER
Corneal dystrophy(CD)
Augen und Sehvermögen
Corneal dystrophy is an inherited eye disorder where abnormal, opaque materials like fats or calcium build up in the cornea, which is the clear outer layer of the eye. This accumulation typically affects both eyes and is non-inflammatory, meaning it does not cause immediate swelling or redness. Over time, these deposits can disrupt the smooth surface of the eye.
Augen · Passing: CLEAR
Legg-Calvé-Perthes disease(LCPD)
Bewegungsapparat
Legg-Calvé-Perthes disease is a serious orthopedic condition affecting the hip joint, primarily in small breed dogs. It occurs when the blood supply to the head of the thigh bone, known as the femur, is spontaneously disrupted. Without blood, this bone tissue dies and collapses, leading to severe joint inflammation and pain.
Roentgen · Passing: A
Color Dilution Alopecia (CDA)(CDA)
Haut und Fell
Color Dilution Alopecia is a genetic skin disorder that affects dogs with diluted coat colors, such as blue, fawn, or lilac. It is caused by an abnormal distribution of pigment within the hair shafts, which makes the hair brittle and prone to breaking. This structural weakness leads to progressive hair loss and leaves the skin more vulnerable to irritation.
Haut · Passing: CARRIER
Mitral valve dysplasia(MVD)
Herz
Mitral valve dysplasia is a congenital heart defect where the mitral valve, which acts as a one-way gate on the left side of the heart, does not form correctly. This malformation prevents the valve from closing tightly, allowing blood to leak backward instead of pumping efficiently to the body. Over time, this leakage strains the heart muscle, which can lead to heart enlargement and eventual heart failure.
Ultraschall · Passing: NORMAL
Hyperuricosuria(HUU)
Nieren
Hyperuricosuria is an inherited metabolic disorder affecting the renal system, specifically how the kidneys process uric acid. Due to a genetic mutation, excess uric acid is excreted into the urine rather than being broken down. This high concentration can cause the acid to crystallize, leading to the formation of painful bladder or kidney stones, also known as uroliths.

Example rule — Ocular anomalies
Both parents must be Clear (valid for 12 months) or better.
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.

Uploaded certificates are AI-extracted and reviewed by our team for authenticity, date, and result.
2 tests are currently mandatory under the relevant breed-club regulations. The most common are Ocular anomalies, Patellar Luxation (PL). Every test must be completed before mating, and the result must fall within the threshold defined by the regulation.
