Health Testing Guide
Which tests are mandatory, how to spot responsible breeders — and what it costs when things go wrong.
For the Rhodesian Ridgeback we've compiled 5 tests required by AKC Parent Club: Rhodesian Ridgeback Club of the United States / Rhodesian Ridgeback Club Deutschland e.V. (RRCD) and 9 additionally recommended tests, drawn from breed-club regulations, the University of PEI (CIDD), and OMIA — weighted by severity and heritability.

In the Rhodesian Ridgeback, there are breed-typical risks for severe conditions such as Degenerative Myelopathy, Juvenile Myoclonic Epilepsy (Rhodesian Ridgeback), as well as joint disorders like Hip Dysplasia (HD) and Elbow Dysplasia (ED). Responsible breeders eliminate these risks through targeted matings and also test for hereditary bleeding disorders such as Haemophilia B (HEMB). Before buying a puppy, ask to see the official test results of both parents: HD must be A–B and ED 0–1, while for Degenerative Myelopathy and Juvenile Myoclonic Epilepsy (Rhodesian Ridgeback), carriers may only be mated with proven clear partners.
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 Rhodesian Ridgeback, AKC Parent Club: Rhodesian Ridgeback Club of the United States / Rhodesian Ridgeback Club Deutschland e.V. (RRCD) requires 5 tests for breeding approval, plus 9 additional recommended tests. 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 don't always predict severity in the puppies. Even so, they're a powerful tool of responsible breeding.
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 meets the Good level and performs 9 additional clinically recommended screenings that reduce risk in this breed.
In addition to Good:
Cleft palate
Andere
A cleft palate is a congenital birth defect where the roof of the mouth fails to fuse properly during development in the womb. This failure leaves an abnormal opening between the oral cavity and the nasal passages. Because these two systems are directly connected, food, liquids, and air cannot be properly separated during swallowing.
Physical examination · Passing: clear
Congenital blindness
Augen
Congenital blindness is a severe or complete loss of vision present from birth, affecting the eyes and the neural pathways connected to the brain. It is caused by developmental abnormalities in key structures like the retina, which is the light-sensitive tissue at the back of the eye, or the optic nerve. These structural defects prevent visual signals from being properly formed or transmitted.
Physical examination · Passing: clear
Cervical vertebral compressive myelopathy(CVCM)
Bewegungsapparat
Cervical vertebral compressive myelopathy, commonly known as Wobbler syndrome, is a condition affecting the spine where the spinal cord in the neck becomes pinched. This compression is caused by malformed neck vertebrae or slipping discs between the bones. Over time, the constant pressure damages the nerve pathways that carry signals from the brain to the limbs.
X-ray
Color Dilution Alopecia (CDA)(CDA)
Haut und Fell
Color Dilution Alopecia is a genetic skin disorder that affects dogs with diluted coat colors, such as blue or grey. It is caused by an abnormal distribution of pigment within the hair shafts, which makes the hair brittle and prone to breaking. This structural weakness leads to progressive hair loss and leaves the skin more vulnerable to irritation.
Skin test · Passing: clear or carrier
Dermoid sinus(DS)
Haut und Fell
A dermoid sinus is a congenital skin defect where a tube-like channel fails to close properly during embryonic development, extending from the skin's surface down into deeper tissues or even the spinal cord. This condition primarily affects the skin and nervous system along the midline of the neck and back. While genetic risk tests exist to screen for the underlying ridge gene duplication, a physical examination by a veterinarian, known as clinical palpation, remains the gold standard for diagnosing an actual sinus.
Physical examination · Passing: clear
Congenital deafness(CHSD)
Nervensystem
Congenital deafness is a hereditary hearing loss present from birth that affects the inner ear's sensory cells, preventing sound signals from reaching the brain. It is usually genetic, occurs more often in certain breeds and is frequently linked to coat patterns such as merle or piebald.
Physical examination · Passing: hearing in both ears
Adult-onset deafness(AOD)
Nervensystem
This condition is a progressive form of hearing loss that affects the auditory system, specifically the sensory cells within the inner ear. Over time, these specialized cells degenerate and lose their ability to transmit sound signals to the brain. Because it is an inherited disorder, this deterioration occurs naturally as the dog matures, even though the outer ear looks completely healthy.
DNA test · Passing: clear or 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.
DNA test · Passing: clear
Primary hypothyroidism
Stoffwechsel
Primary hypothyroidism is an endocrine disorder where the thyroid gland, located in the neck, fails to produce enough thyroid hormones. This hormone deficiency is usually caused by the immune system mistakenly attacking the gland or by the gradual replacement of thyroid tissue with fat. Because these hormones regulate how the body uses energy, a shortage slows down the dog's entire metabolism.

We take mandatory tests from official breed regulations, build the recommended health standard from veterinary databases — and cross-check every uploaded certificate against the dog's profile using AI.
L1 = core standard: the club's required tests where its rules set them, otherwise the recommended health standard for the breed. L2 = additionally recommended or clinically indicated. L3 = lower prevalence. Every assignment carries a source and confidence rating.
VDH breeding regulations, CIDD (University of PEI), OMIA (University of Sydney), curated veterinary input.
Uploaded certificates are read by AI and checked for date, result, and consistency with the dog's profile — our team reviews anything inconclusive.
Not every dog of this breed is affected to the same degree – but these extreme-breeding traits are part of the Rhodesian Ridgeback's breed type: Ridge & dermoid sinus. How strongly an individual dog is affected depends on breeding choices. What to look out for is explained on the linked pages.
