Bridget Bodine, of DeCoverly Kennels, recently posted this on her Facebook page:
Confusion about the PennHIP method, the reports, and how to interpret them has been rampant since it’s inception. Much of the confusion stems from two sources. First is PennHIP’s use of the term “DJD” (degenerative joint disease) instead of it’s alternative and more common name: osteoarthritis. Hip dysplasia and DJD/arthritis are not the same thing. One is abnormal formation of the hip joint, the other is arthritis. Arthritis in the hip is usually caused by hip dysplasia, but it can also be caused by injury or infection.
The second source of confusion is that people instinctively try to translate PennHIP results into a diagnostic/OFA context, which is impossible. PennHIP is the only hip dysplasia control scheme in the world that does not diagnose hip dysplasia.
We think Bridget’s plan to OFA the .8 dog is a great idea, but results from one dog don’t give you much to go on so we have made the following proposal. We hope they see the value in taking us up on our offer, especially the potential for educational benefits regarding PennHIP for all concerned.
We read your post regarding PennHIP results. It is clear that you don’t understand the difference between dysplasia and DJD. DJD is not dysplasia. DJD is arthritis. The terms DJD and dysplasia are not interchangeable, so when you say “no dysplasia” you are literally saying the dog has normal hips and would pass an OFA. PennHIP does not assess the hip for the presence of dysplasia. All other dysplasia control methods in the world, OFA, FCI, BVA, etc., diagnosis the presence or absence of dysplasia.
In the interest of furthering knowledge about PennHIP we make the following offer. We will pay the OFA fee for diagnosis of dysplasia for all 30 of the recent dogs on your list. You already have the x-rays required for the OFAs as part of your PennHIP submissions. Have your vet submit them to OFA along with the applications, have them entered into the OFA’s open database, and we’ll pay the $450 OFA fee. With passing OFAs you can accurately state the dogs have no dysplasia.
This knowledge can only serve to help all of us make more informed breeding decisions that contribute to a better future for the dogs.
