Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Airedale Terrier we have compiled 14 mandatory and 9 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 Airedale Terrier receives a grade of C, as it carries an above-average genetic burden with 9 mandatory health tests. The eyes are particularly at risk due to conditions such as Progressive Retinal Atrophy (PRA) and cataracts, which require regular screening. Furthermore, hip dysplasia (HD) and elbow dysplasia (ED) must be consistently monitored to prevent painful joint diseases.
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 Airedale Terrier we track 14 mandatory tests plus 9 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.

In addition to mandatory tests:
Ectropion / Entropion
Augen
These are structural eyelid abnormalities affecting a dog's eyes. In cases of entropion, the eyelid rolls inward, causing the eyelashes or fur to rub painfully against the surface of the eyeball. In ectropion, the eyelid sags or rolls outward, leaving the sensitive inner lining of the eye exposed and unprotected.
Passing: CLEAR
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
Retinal Dysplasia(RD)
Augen
Retinal dysplasia is a congenital condition affecting the eyes, where the retina (the light-sensitive tissue at the back of the eye) does not develop properly during growth in the womb. This abnormal development leads to structural defects like folds or gaps in the retinal layers. Because the retina is responsible for sending visual signals to the brain, these imperfections can impair normal vision.
Augen · Passing: CLEAR
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
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
Lens luxation(PLL)
Augen und Sehvermögen
Lens luxation is an inherited eye disorder where the lens slips out of its normal position because the supporting fibers holding it in place weaken or break. When the lens shifts, it can block the natural drainage of fluid within the eye. This blockage causes a rapid, painful buildup of pressure called glaucoma, which can lead to permanent blindness if left untreated.
Augen · Passing: CLEAR
Pulmonary stenosis(PS)
Herz
Pulmonary stenosis is a congenital heart defect characterized by a narrowing of the pulmonary valve or the outflow tract leading from the heart to the lungs. This narrowing restricts blood flow, forcing the right side of the heart to work much harder to pump blood. Over time, this constant strain can lead to thickening of the heart muscle and potential heart failure.
Passing: NORMAL
Hypothyroidism
Hormonelles und Stoffwechsel
Hypothyroidism is an endocrine disorder where the thyroid gland, located in the neck, fails to produce enough thyroid hormones. These hormones are essential for regulating the body's metabolic rate, which is the speed at which cells convert nutrients into energy. When hormone levels are too low, the dog's entire metabolism slows down, affecting multiple organ systems.
Koerperfluessigkeiten · Passing: CARRIER
Cerebellar abiotrophy(CA)
Nervensystem
Cerebellar abiotrophy is an inherited neurological disorder affecting the brain, specifically the cerebellum, which regulates balance and movement coordination. In affected dogs, the nerve cells in this region prematurely degenerate and die off. This progressive cell loss disrupts the brain's ability to control smooth physical movements.

Uploaded certificates are AI-extracted and reviewed by our team for authenticity, date, and result.
14 tests are currently mandatory under the relevant breed-club regulations. The most common are DNA-Identitätsnachweis, Ocular anomalies, Cone-rod dystrophy 3 (crd3) (crd3). Every test must be completed before mating, and the result must fall within the threshold defined by the regulation.
