Hi
Better positioning might make a difference to the laxity and pull the ball into the socket but it won't change the arthritic changes seen on the femoral heads and necks. I understand that this type of arthritis is caused through the extra wear the joints suffer due to their genetic laxity. As the joint gets damaged through wear, the body attempts to repair the damage and manufactures extra bone to try to stabilise the joint. What you are seeing is the product of wear on loose hips over a few years. This is the reason that many dogs have little or no DJD (Degenerative Joint Disease or arthritis) when they are screened as youngsters but go on to develop it with age. I would be very interested to see the plates from 3 years ago as they could be a really good illustration of how loose hips change over time. Many people assume that once the dog is screened it's hips always stay the same, but if there is any extra room for movement in the joint that joint will change as it gets tired and worn and the body carries out repairs. Dogs with completely tight and perfect hips will not have the same changes as there will be no excess wear over time.
