Yes you should have the x-rays done right away. If the hips are bad, radiographically now you have big problems. They only get worse as the dog ages. If your dog does have dysplasia she should still work for a water dog. Swimming is good exercise and easy on the joints. I wouldn' t reccommend any upland hunting with her. You won' t likely be able to hunt her many days in a row though. It all depends on how bad the radiographs are and how much pain she is in. If they come back positive I would get her on a glucosamine/chondroitan supplement right away. Cosequin is the only one I reccommend, it is expensive but it is also the only one with any scientific research behind it. The surgeries do work fairly well. For $3000 they are talking total hip replacement. At her age a TPO, or triple pelvic osteotomy would likely be a better option. The pelvis is cut in three places and rotated then plated back together so the hip socket fits over the ball better. This usually works very well in young dogs and should be about half the cost of a total hip. Like I said, get the x-rays done now and let us know how they look.
