Health Testing Guide
Which tests matter, how to spot responsible breeders — and what it costs when things go wrong.
For the Australian Stumpy Tail Cattle Dog we've compiled 3 tests in the recommended health standard and 5 additionally recommended tests, drawn from veterinary databases such as CIDD (University of PEI) and OMIA — weighted by severity and heritability.

With the Australian Stumpy Tail Cattle Dog, you should pay particular attention to congenital deafness (CHSD), progressive retinal atrophy, and cataracts. A responsible breeder tests their breeding stock for these core risks and additionally screens for hip dysplasia (HD), elbow dysplasia (ED), primary lens luxation (PLL), degenerative myelopathy, and cystinuria. Before buying, ask to see proof that both parent animals have normal bilateral hearing and are clear of cataracts and primary lens luxation (PLL). For genetic tests such as progressive retinal atrophy, degenerative myelopathy, and cystinuria, a carrier status is only acceptable if the respective mating partner is proven to be clear.
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. The recommended health standard for the Australian Stumpy Tail Cattle Dog covers 3 tests, plus 5 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 5 additional clinically recommended screenings that reduce risk in this breed.
In addition to Good:
Lens luxation(PLL)
Augen
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.
Eye examination · Passing: clear
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.
X-ray · Passing: ED 0–1
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.
X-ray · Passing: HD A–C
Degenerative Myelopathy(DM)
Nervensystem
Degenerative Myelopathy is a progressive disease of the spinal cord where the protective sheath around the nerves slowly breaks down. This deterioration disrupts the vital communication signals between the brain and the muscles of the hind limbs. Over time, this lack of signal transmission leads to a complete loss of muscle control in the back legs.
DNA test · Passing: clear or carrier
Cystinuria(Cyst-1a)
Nieren
Cystinuria is an inherited metabolic disorder affecting the kidneys, where the body fails to reabsorb an amino acid called cystine. Instead of being filtered back into the bloodstream, cystine builds up in the urine. Over time, this high concentration causes the amino acid to crystallize, forming painful stones in the bladder and urinary tract.

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.

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 Australian Stumpy Tail Cattle Dog's breed type: Screw tail. How strongly an individual dog is affected depends on breeding choices. What to look out for is explained on the linked pages.
