Uploaded health tests
Great level
Sterling Built Boerboels reports to performing the health tests below on their breeding dogs. Ask your breeder about the tests performed on the parents of your litter. Learn more about health testing for Boerboels.
Hip Dysplasia
Hip testing reduces the chance of passing down hip dysplasia, which is primarily found in large breed dogs and can cause hip pain and the eventual loss of the function of the hip joint.
Elbow Dysplasia Finals (OFA, BVA, SV, FCI)
Elbow testing reduces the chance of passing down elbow dysplasia, which is primarily found in large breed dogs and can cause arthritis in the elbow joint and front leg lameness.
Cardiac Evaluation (registered with OFA)
Heart testing reduces the chance of passing down congenital heart disease, which can cause a range of symptoms ranging from trouble exercising to heart failure.
DNA Disease Panel
Genetic testing reduces the chance of passing down a wide variety of hereditary diseases of differing prevalence and severity such as Progressive Retinal Atrophy (an eye disease) and Von Willebrand's Disease (a blood disease).
Health testing is one key piece of responsible breeding and is performed on breeding dogs to prevent the presence of heritable conditions in their puppies.
