Which is Better, PennHIP or OFA, and why?
answer this, here's a good analogy written by Linda Lipford:
dogs hips and the surrounding hip area were the wheel area on your car:
would look at the wheels themselves to make sure it is the correct size
for your car and had the proper tread. They would look at
rotors, calipers and brake pads to make sure that they are smooth and
unworn and installed properly. And if something was not correct size or
worn or not fitting properly, they would grade it based on how
incorrect or worn it is.
would look at how tightly that wheel fits on the rim. Are all
the bolts screwed in tight so it does not wobble.
if you have a car with the proper perfect wheels, brakes etc, and the
lugnuts are not tight and the wheel wobbles going down the highway,
eventually it will wear those perfect tires and surrounding area out
if your car has nice tight tires on the rim, but some of the other
parts are not correctly spec'd, you could also eventually wear out some
parts earlier than expected."
the answer is that PennHIP and OFA measure different things, and both
are important. Ideally, every breeding dog should have both evaluations
done to provide the most accurate picture.
