6 month old Labrador Retriever

Discussion

This syndrome is caused by a gene that has effects on both the skeleton and the eye. This dog had cataracts and retinal detachment at the time the radiographs were taken. The bones of the appendicular skeleton are shortened, and the joints, especially the elbow and hip, are abnormal. The radius is usually curved and the distal metaphyses of the radius and ulna are widened. Published reference ranges for diagnosing this condition are radial length of less than 3 cm and ulnar less than 3.7 cm at 16 days of age. The shape of the humerus is also different between affected and unaffected dogs.
