Our health testing levels for the Saint Bernard
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 10 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Gastric dilatation-volvulus(GDV)
Andere
Gastric dilatation-volvulus, commonly known as bloat, is a severe condition affecting the stomach and digestive system. It occurs when the stomach fills with gas and twists on itself, trapping the gas and blocking blood flow to vital organs. This twisting can rapidly lead to tissue damage and cardiovascular shock if not treated immediately.
Roentgen
Dermoids
Augen
A dermoid is a benign, congenital growth where normal skin tissue, which can include hair follicles and glands, mistakenly develops in abnormal locations on the eye. This typically affects the cornea, which is the clear outer surface of the eye, or the conjunctiva, the pink membrane lining the eyelids. Because this misplaced skin tissue often grows hair, it causes constant irritation to the eye's surface.
Physisch
Exposure keratopathy syndrome (exophthalmos, lagophthalmos, and/or macroblepharon)(EKS)
Augen und Sehvermögen
This condition involves chronic damage to the cornea, which is the clear protective outer layer of the eye. It occurs when the eyelids cannot fully close to moisten the eye, often due to protruding eyeballs, incomplete eyelid closure, or an abnormally large eyelid opening. Without proper moisture, the delicate surface of the eye becomes dry, inflamed, and vulnerable to injury.
Augen
Cataract(HC)
Augen und Sehvermögen
A cataract is a progressive clouding of the lens inside the dog's eye, which is the clear structure that focuses light onto the retina at the back of the eye. When the lens becomes cloudy or opaque, it blocks light from entering, gradually impairing the dog's vision. If left untreated, this condition can eventually lead to complete blindness in the affected eye.
Augen
Elbow Dysplasia(ED)
Bewegungsapparat
Elbow dysplasia is a developmental disorder of the musculoskeletal system where the three bones forming the elbow joint do not fit together properly. This misalignment causes abnormal friction and wear on the joint cartilage, eventually leading to painful, chronic joint inflammation and arthritis. It is a complex genetic condition influenced by multiple genes.
Roentgen · Passing: Grade 1 or better
Hip dysplasia(HD)
Bewegungsapparat
Hip dysplasia is an inherited skeletal disorder where the ball and socket of the hip joint do not fit together properly. Instead of sliding smoothly, the bones rub and grind against each other, wearing down the protective cartilage. Over time, this chronic friction causes joint instability, painful inflammation, and progressive arthritis, which is the gradual wear and tear of the joint.
Roentgen · Passing: C or better
Ehlers-Danlos syndrome (Cutaneous asthenia)(EDS)
Haut und Fell
Ehlers-Danlos syndrome, also known as cutaneous asthenia, is an inherited connective tissue disorder that affects the skin and joints. It is caused by a genetic defect in collagen, which is the primary structural protein that provides strength and elasticity to tissues. Because of this defect, the skin lacks its normal structural integrity, making it unusually fragile, thin, and loose.
Haut
Dilated cardiomyopathy(DCM)
Herz und Kreislauf
Dilated cardiomyopathy (DCM) is a severe disease of the heart muscle where the heart's chambers become stretched and enlarged. This stretching thins the heart walls, making it difficult for the heart to pump blood effectively to the rest of the body. Over time, this decreased pumping ability can lead to fluid buildup in the lungs or abdomen.
Ultraschall
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
Bleeding disorder
Stoffwechsel
A bleeding disorder is a malfunction of the circulatory system where the blood cannot clot properly due to missing or defective clotting factors or platelets, which are the cells responsible for plugging damaged blood vessels. This impairment prevents the body from effectively sealing wounds, leading to prolonged internal or external bleeding.
These levels are a comparison framework, not an official certification. They help compare breeding programs at a glance.
