Our health testing levels for the Chinese Crested Dog
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 4 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
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 · Passing: Clear or Carrier
Multiple system degeneration, SERAC1-related(CMSD)
Nervensystem
This is a severe, inherited disorder of the nervous system caused by a genetic mutation in the SERAC1 gene. The mutation disrupts cellular lipid metabolism, which is the process cells use to break down and use fats. This disruption leads to progressive damage to nerve cells in both the brain and the spinal cord.
Passing: Clear or Carrier
Neuronal Ceroid Lipofuscinosis(NCL)
Nervensystem
Neuronal Ceroid Lipofuscinosis (NCL) is an inherited metabolic disorder that affects the nervous system. It occurs when nerve cells in the brain and eyes are unable to properly recycle cellular waste, leading to a harmful buildup of these materials that permanently damages the tissues.
DNA · Passing: CARRIER
Hyperuricosuria(HUU)
Nieren
Hyperuricosuria is an inherited metabolic disorder affecting the renal system, specifically how the kidneys process uric acid. Due to a genetic mutation, excess uric acid is excreted into the urine rather than being broken down. This high concentration can cause the acid to crystallize, leading to the formation of painful bladder or kidney stones, also known as uroliths.
Koerperfluessigkeiten · Passing: Clear or Carrier
These levels are a comparison framework, not an official certification. They help compare breeding programs at a glance.
