I was thinking fair also, but it is up to the 3 vets who read the xrays.
Nobody can say whether she will or will not have issues later in life. OFA rating will not affect her quality of life, just if she is breeding quality or not.
I have seen hips on dogs look so bad you wonder how they walk, much less run and play, and basically good hips and the dog doesn't want to move. Each dog has its own pain capacity if there is pain.
Will be interesting what OFA grades your girl.
