Our health testing levels for the Labrador Retriever
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 11 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Cleft palate
Allgemeine Fitness und Anatomie
A cleft palate is a congenital birth defect where the roof of the mouth fails to fuse properly during development in the womb. This failure leaves an abnormal opening between the oral cavity and the nasal passages. Because these two systems are directly connected, food, liquids, and air cannot be properly separated during swallowing.
Physisch · Passing: CLEAR
Cervical vertebral compressive myelopathy(CVCM)
Bewegungsapparat
Cervical vertebral compressive myelopathy, commonly known as Wobbler syndrome, is a condition affecting the spine where the spinal cord in the neck becomes pinched. This compression is caused by malformed neck vertebrae or slipping discs between the bones. Over time, the constant pressure damages the nerve pathways that carry signals from the brain to the limbs.
Roentgen · Passing: A
Hereditary myopathy - Labrador retriever/Bouviers des Flandres myopathy(CNM)
Bewegungsapparat
This is an inherited muscle disease affecting the skeletal muscles of Labrador Retrievers and Bouviers des Flandres. It is caused by a genetic defect that prevents muscle fibers from developing normally, leading to progressive muscle wasting where the muscles gradually shrink and weaken.
DNA · Passing: CARRIER
Hemophilia
Herz und Kreislauf
Hemophilia is an inherited blood clotting disorder affecting the circulatory system, where the body lacks specific proteins needed for coagulation, which is the process of blood clotting. Because the blood cannot clot properly, even minor injuries can lead to prolonged internal or external bleeding. This condition is inherited through an X-linked genetic trait, meaning it primarily affects male dogs.
Koerperfluessigkeiten · Passing: CLEAR
Diabetes mellitus(DM)
Hormonelles und Stoffwechsel
Diabetes mellitus is a chronic metabolic disorder affecting the endocrine system, specifically the pancreas, which fails to produce enough insulin. Insulin is a vital hormone that allows the body's cells to absorb glucose, or sugar, from the bloodstream to use as energy. Without sufficient insulin, sugar builds up in the blood while the body's cells are starved of fuel.
Koerperfluessigkeiten · Passing: CLEAR
Cerebellar abiotrophy(CA)
Nervensystem
Cerebellar abiotrophy is an inherited neurological disorder affecting the brain, specifically the cerebellum, which regulates balance and movement coordination. In affected dogs, the nerve cells in this region prematurely degenerate and die off. This progressive cell loss disrupts the brain's ability to control smooth physical movements.
DNA · Passing: CLEAR
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: CARRIER
Epilepsy(IE)
Nervensystem
Epilepsy is a chronic disorder of the brain and nervous system where abnormal electrical activity causes sudden, temporary disruptions in normal brain function. These disruptions lead to repeated seizures, which are involuntary changes in body movement, sensation, or behavior. Because the underlying cause is often complex, the brain's electrical signaling remains permanently prone to these sudden misfires.
Physisch
Globoid cell leukodystrophy (galactocerebrosidosis)(GCL)
Nervensystem
Globoid cell leukodystrophy is an inherited metabolic disorder affecting the nervous system, caused by a deficiency in an essential enzyme. This deficiency leads to the buildup of harmful substances that destroy myelin, which is the protective sheath surrounding nerve fibers in the brain and spinal cord. Without this protective covering, the nerves cannot transmit signals properly, resulting in progressive neurological decline.
DNA · Passing: CLEAR
Portosystemic hepatic encephalopathy(PSS)
Stoffwechsel
This is a neurological condition caused by liver dysfunction, typically occurring when abnormal blood vessels bypass the liver. Because the liver cannot filter toxins from the bloodstream, these harmful substances build up and directly affect the brain. This lack of proper filtration leads to central nervous system dysfunction.
Passing: NORMAL
Skeletal Dysplasia 2(SD2)
Zähne und Knochen
Skeletal Dysplasia 2 (SD2) is an inherited bone growth disorder affecting the skeletal system. It causes a mild form of disproportionate dwarfism, where the long bones of the legs do not grow to their normal length. The torso and head develop normally, resulting in a slightly uneven body shape.
