My point is that I think it can be helpful to get the hips graded separately. Though the PH% ranking is based on the poorer hip, at least you have information on both hips in the report. So no, OFA and PH are not classifid exactly the same way. Unless OFA has changed, you get a report based on the poorer hip. And not only is the report based on the poorer hip, you have no idea how good the better hip is.
My suggestion for an independant consultant if the prelim OFA and final OFA don't correlate at all is for the reason that each hip can be looked at individually (ie: Wallace).
I don't have my reports handy, but I don't think I have had 2 hips that were significantly different...especially to the point that it would change a decision.
Just an FWI, Penn Hip gives its % on the lowest scoring hip. That is exactly the same in classification as OFA, scoring on the lowest hip. The only different is you have the number on each hip but... more

I understand what you mean Cris. I had a girl go from a prelim of excellant to a final of fair with OFA. I called Dr. Keller to discuss this drop. He said that only one hip was fair, the other would... more
