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:
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: Free
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: Clear or Carrier
Elbow Dysplasia(ED)
Bewegungsapparat
Elbow dysplasia is a developmental disorder of the musculoskeletal system where the three bones forming the elbow joint do not fit together properly. This misalignment causes abnormal friction and wear on the joint cartilage, eventually leading to painful, chronic joint inflammation and arthritis. It is a complex genetic condition influenced by multiple genes.
Roentgen · Passing: 0
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: B or better
Hemophilia B(HEMB)
Stoffwechsel
Haemophilia B is a severe, X-linked genetic bleeding disorder affecting the blood circulatory system. It is caused by a deficiency in clotting factor IX, which is a specific protein necessary for blood to clot properly. Without enough of this protein, the normal clotting process fails, leading to prolonged or uncontrolled bleeding.
Passing: CLEAR

Example rule — Hip dysplasia (HD-FCI)
Both parents must be tested for Hip dysplasia (HD-FCI) and show a passing result.
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.

Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the English Coonhound we have compiled 0 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 English Coonhound is a robust working breed, but as a large dog, it remains susceptible to hip dysplasia (HD) and life-threatening gastric dilatation-volvulus (GDV). Since there are few standardized genetic tests established for this breed, buyers must pay close attention to the clinical health records of the parent dogs. Coonhound paralysis, a rare neurological condition, should also be kept in mind.
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 English Coonhound we track 0 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.
