Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Flat-Coated Retriever we have compiled 3 mandatory and 5 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 Flat Coated Retriever receives a grade of C. While joint issues such as elbow dysplasia (ED) are well-controlled through mandatory health tests in breeding programs, the breed remains susceptible to hip dysplasia (HD) and carries an above-average risk for aggressive cancers such as malignant histiocytosis. Prospective buyers should pay close attention to a long-lived and healthy ancestral line.
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 Flat-Coated Retriever we track 3 mandatory tests plus 5 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 5 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Ocular anomalies
Augen
Ocular anomalies are a group of congenital malformations, meaning they are present from birth, that affect various structures of the dog's eye such as the retina, lens, or cornea. These developmental defects alter the normal structure of the visual system, potentially impacting how light is focused or how the eye functions. The condition is complex and can range from minor physical irregularities to severe structural changes.
Physisch · Passing: Frei von zuchtausschließenden erblichen Augenerkrankungen
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
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: Frei von postpolarem Katarakt
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.
Roentgen · Passing: C (leicht) oder besser
Histiocytosis(MH)
Tumor
Histiocytosis is a severe disorder of the immune system where specific white blood cells, called histiocytes, multiply abnormally. These cells normally help protect the body, but their uncontrolled growth can lead to tumors or tissue damage in various organs, including the skin, lungs, spleen, and lymph nodes. Depending on the form, it can be localized to the skin or spread aggressively throughout the body's internal systems.

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.
3 tests are currently mandatory under the relevant breed-club regulations. The most common are Elbow Dysplasia (ED), Patellar Luxation (PL), Progressive Retinal Atrophy (prcd-PRA) (PRA). Every test must be completed before mating, and the result must fall within the threshold defined by the regulation.
