|Well, I actually prefer x-rays (OFA), only because anyone can SEE the issues with an x-ray. However, positioning and degree of sedation can certainly make a huge difference in the whole picture so it pays to get them done with a really experienced vet.
Penn Hip is more subjective, IMO. Lots of what is being felt can be interpreted differently by different vets...you can't actually see what is there.
IMO, HD is much, much more than laxity of the femur head... you can have nice, tight femur heads with major arthritis which will make the Penn Hip not so much of a good thing. Case in point...French Bulldogs. They have such extreme muscle mass that their hips are always tight! I had one who was extremely tight and the vet said they would be perfect...x-rays showed the femur heads weren't even IN the sockets!! OFA graded severe.
Ideally... both, but using only one I would chose OFA. If you have an experienced vet and you are not doing the hips for breeding considerations, you can have the x-rays done and have your own vet read them and not send them to OFA.
