| Those are the current ratings - were they the same when they x-rayed at a younger age 20+ years ago? (OFA used to certify at one year also, 20+ years ago or so.) The *advantage* to OFA (or what makes it a LITTLE bit more thorough) is that they have 3 readers instead of one. As to their requirements, etc., I think the jury is still very much out on that! (As vs. PennHip, etc.) I've had a dog show laxity on x-ray in one hip that OFA'd Good . . .
