Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Golden Retriever we have compiled 7 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 Golden Retriever is a wonderful family dog, but carries an above-average genetic burden. Hip dysplasia (HD) and elbow dysplasia (ED) in particular are serious orthopedic concerns that require rigorous breeding selection. Furthermore, eye conditions such as Progressive Retinal Atrophy (PRA) must be actively ruled out through genetic testing.
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 Golden Retriever we track 7 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.
A breeder at the Great level performs all mandatory tests plus 9 additional clinically recommended screenings that reduce risk in this breed.
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
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
Distichiasis
Augen und Sehvermögen
Distichiasis is an eye condition where extra eyelashes grow from the meibomian glands, which are the oil glands along the edge of the eyelid. These abnormal hairs point inward and rub directly against the cornea, the clear outer surface of the eye. This constant friction causes mechanical irritation and can damage the sensitive ocular surface.
Augen · Passing: CLEAR
Duchenne muscular dystrophy(DMD)
Bewegungsapparat
This is a severe, inherited muscle disorder caused by a lack of dystrophin, which is a crucial protein that helps keep muscle cells intact. Without this protein, both the skeletal muscles used for movement and the cardiac muscle of the heart progressively weaken and break down.
DNA · Passing: CLEAR
Atopy(CAD)
Haut und Fell
Atopy is a chronic allergic skin disease where a dog's immune system overreacts to common environmental substances like pollen, mold spores, and dust mites. This inappropriate immune response damages the natural protective barrier of the skin, leading to persistent inflammation and irritation. It primarily affects the skin, which is the body's largest organ system.
Haut
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
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.
Physisch
Hypomyelination(HYM)
Nervensystem
This is an inherited neurological disorder affecting the central nervous system, where the protective myelin sheath that insulates nerve fibers fails to develop properly. Without this adequate insulation, nerve signals cannot travel efficiently between the brain and the body. This disruption leads to impaired coordination and involuntary muscle movements.

7 tests are currently mandatory under the relevant breed-club regulations. The most common are Progressive Retinal Atrophy 1 (Golden Retriever) (GR-PRA1), Progressive Retinal Atrophy 2 (Golden Retriever) (PRA-GR2), Retinal Dysplasia (RD). Every test must be completed before mating, and the result must fall within the threshold defined by the regulation.
