Our health testing levels for the Old German Shepherd 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 3 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Lumbosacral Transitional Vertebra(LTV)
Bewegungsapparat
Übergangswirbel, also known as lumbosacral transitional vertebrae (LSTV), is a congenital skeletal malformation where a vertebra at the junction of two spinal sections—usually the lower back and the pelvis—develops abnormally, sharing characteristics of both areas. This anatomical variation can cause instability or uneven pressure in the lower spine. It is frequently identified during standard hip dysplasia screening radiographs, which evaluate the same pelvic region.
Roentgen · Passing: LÜW 0 or LÜW 1
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
MDR1 gene mutation (drug sensitivity)(MDR1)
Nervensystem
This genetic condition affects the nervous system by impairing the blood-brain barrier, which normally acts as a protective filter for the brain. Due to a missing transport protein, certain common medications can cross this barrier unchecked and accumulate in the brain. This can lead to severe, life-threatening neurological damage.
Passing: Clear or Carrier
These levels are a comparison framework, not an official certification. They help compare breeding programs at a glance.
