Hello, the international method of scoring with ofa standard is to take 2 standard x-rays (ventral dorsal and ventral dorsal frog) at 24 months of age and score the dog by the position of the hip in relation to the femoral head and the degree of inflammation of the joint. However, it is clinically late to diagnose an adult dog at 2 years of age, so if you notice abnormal posture in the hind legs of walking, promptly visit your vet.
