Osteochondrodysplasia is a skeletal developmental disorder that appears very early in puppies. It causes visible bone deformities, such as shortened or curved limbs, enlarged joints, a flattened rib cage, and sometimes a shortened lower jaw. Radiographs reveal abnormalities in ossification, particularly in the epiphyses and vertebrae. Affected puppies show marked joint stiffness that decreases with age, but mobility remains limited. In the long term, osteoarthritis is common and has a lasting impact on quality of life.
This test is also recommended for the Papillon as part of the Flemish government breeding program (see the official program).
