Our health testing levels for the Canadian Shepherd
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 2 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Malignant Hyperthermia(MH)
Stoffwechsel
Malignant hyperthermia, also known as Narkoseüberempfindlichkeit, is an inherited skeletal muscle disorder caused by a genetic mutation in the RYR1 gene. This mutation disrupts how calcium is regulated within the muscle cells, causing them to contract uncontrollably when triggered. These intense spasms generate a rapid, life-threatening rise in body temperature, typically brought on by specific anesthetic gases or extreme physical stress.
DNA · Passing: CLEAR
Mucopolysaccharidosis Type VII(MPS VII)
Mucopolysaccharidosis Type VII (MPS VII) is an inherited metabolic disorder belonging to a group called lysosomal storage diseases. It occurs when a deficiency in a specific enzyme prevents the body from breaking down complex sugar molecules, leading to a harmful buildup of waste products inside cells. This accumulation causes progressive damage to multiple organ systems, particularly the skeleton and connective tissues.
Passing: CARRIER
These levels are a comparison framework, not an official certification. They help compare breeding programs at a glance.
