Our health testing levels for the Leonberger
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 1 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Leukoencephalomyelopathy (LEMP)(LEMP)
Nervensystem
Leukoencephalomyelopathy (LEMP) is an inherited neurological disease that affects the brain and spinal cord. It causes the progressive breakdown of myelin, which is the protective coating around nerve fibers that helps transmit signals. Without this coating, the dog's central nervous system cannot properly send messages to the rest of the body.

These levels are a comparison framework, not an official certification. They help compare breeding programs at a glance.
