Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Dalmatian we have compiled 6 mandatory and 11 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 Dalmatian receives a grade of C because the breed is affected by several specific health issues. Congenital unilateral or bilateral deafness is a particularly serious concern, which is why an audiometric hearing test (BAER) should be mandatory for every puppy. Furthermore, the breed-typical hyperuricosuria often leads to painful urinary stones, necessitating a strict, low-purine diet.
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 Dalmatian we track 6 mandatory tests plus 11 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 11 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Acute Respiratory Distress Syndrome (Dalmatian)(ARDS)
Atmung
This is an inherited lung disease in Dalmatian puppies that causes progressive damage to the alveoli, which are the tiny air sacs in the lungs responsible for absorbing oxygen. As these air sacs break down, the lungs can no longer transfer oxygen to the bloodstream, leading to sudden and severe respiratory failure.
Roentgen · Passing: Clear or Carrier
Laryngeal Paralysis(LP)
Atmung
Laryngeal paralysis is a respiratory disorder where the nerves controlling the muscles of the larynx, or voice box, fail to function properly. This failure prevents the vocal folds from opening when the dog inhales, which severely restricts airflow into the windpipe and lungs. Over time, this lack of proper movement can lead to significant breathing difficulties.
Roentgen · Passing: A
Progressive Retinal Atrophy (PRA)(PRA)
Augen
Progressive Retinal Atrophy (PRA) is an inherited eye disease that affects the retina, which is the light-sensitive layer of tissue at the back of the eye. In this condition, the specialized cells responsible for detecting light, known as photoreceptors, gradually degenerate and die. Because these cells cannot recover or be replaced, the disease slowly but inevitably leads to complete blindness.
Passing: CARRIER
Primary Open-Angle Glaucoma(POAG)
Augen und Sehvermögen
Primary open-angle glaucoma is an inherited eye disease where the natural fluid inside the eye cannot drain properly. This fluid buildup causes a gradual increase in pressure within the eyeball, which eventually damages the optic nerve, the connection between the eye and the brain. Without management, this pressure leads to permanent blindness.
Augen · Passing: CLEAR
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: CLEAR
Pannus (Chronic Superficial Keratitis)(CSK)
Augen und Sehvermögen
Pannus, or chronic superficial keratitis, is an immune-mediated disease affecting the cornea, which is the clear outer surface of the eye. In this condition, the dog's immune system mistakenly attacks the cornea, causing blood vessels and dark pigment to grow across it. This process is worsened by exposure to ultraviolet (UV) light and can eventually block the dog's vision.
Augen · Passing: CLEAR
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: CARRIER
Globoid cell leukodystrophy (galactocerebrosidosis)(GCL)
Nervensystem
Globoid cell leukodystrophy is an inherited metabolic disorder affecting the nervous system, caused by a deficiency in an essential enzyme. This deficiency leads to the buildup of harmful substances that destroy myelin, which is the protective sheath surrounding nerve fibers in the brain and spinal cord. Without this protective covering, the nerves cannot transmit signals properly, resulting in progressive neurological decline.
DNA · Passing: CARRIER
Peripheral neuropathy(PN)
Nervensystem
This is a genetic disorder affecting the peripheral nervous system, which consists of the nerves connecting the brain and spinal cord to the rest of the body. In affected dogs, the protective outer coating of these nerves degrades, disrupting the electrical signals sent to muscles and organs. This leads to progressive muscle weakness and loss of coordination.
Passing: CARRIER
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.
Koerperfluessigkeiten · Passing: CARRIER
Urolithiasis
Nieren
Urolithiasis is the formation of mineral stones within the urinary tract, which includes the kidneys, bladder, and connecting tubes. These solid crystal clusters develop when minerals in the urine clump together instead of dissolving. Over time, these stones can irritate the sensitive lining of the urinary system or completely block the flow of urine.

Uploaded certificates are AI-extracted and reviewed by our team for authenticity, date, and result.
6 tests are currently mandatory under the relevant breed-club regulations. The most common are DNA-Identitätsnachweis, Zahn- und Bissbewertung, Hip dysplasia (HD). Every test must be completed before mating, and the result must fall within the threshold defined by the regulation.
