I'm certainly not an expert here. But, our first sign with Sissy was at about 11 months old with a skipping type of motion that she would do with her back leg when in a moderate run. Thankfully, her's is a mild case and adding glucosamine to her diet (Missing Link +) has helped tremendously.
Angel's legs are rock solid and she is quite the jumper. At 6 months old, the vet was a little concerned that her knees were loose, but at a year she was fine.
