Parent health testing
Great level
Mastini Sierra Pyrenean Mastiffs 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 Pyrenean Mastiffs.
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.
Patellar Luxation
Knee testing reduces the chance of passing down Patellar Luxation, which results in the kneecap becoming displaced or dislocated and can cause mild to severe joint pain.
Vet Wellness Exam
A breeder may perform additional tests on their dogs that do not fall into these general categories. These tests may be more uncommon or very specific to a particular breed.
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).
