They may still have it or go on to show symptoms sadly, although not all do, some satins and carriers never develop the disease. My 2 were 2.5 and 3.5 years old when diagnosed, we only discovered Shelly had it at 3.5 because I did a Halloween shoot with a pumpkin and she ate quite a bit, the amount of phosphorus in it caused a calcium crash leading to her to start limping and bunny hopping, otherwise we may never have known! They really are masters at hiding pain and illness.
It would be a good idea to have them xrayed as a precaution, its what I plan on doing with any future satins or carriers I end up with.
