PennHip Vs. OFA the differences, and which is better? Do you do both? Which one do you prefer, and why? I would like to post as much info here as possible on this subject. Please as always feel free to share any info you may know or have. Thanks!
Will be adding more soon!
We started using PennHIP on our dogs 10 years ago and have PennHIP tested about 100 dogs. Initially the results were not very promising, the average DI was 0,68 and about 20% of the Boerboels tested already had signs of DJD. These days (we have 22 dogs), it shows a very big improvement, the average DI (in our dogs) has decreased to 0,41, and there has been no dog with DJD for the last 4 years.
I do not know whether I can solely contribute the improvement to sticking to the advice from PennHIP, I rather think that it also is a case of the dog´s diet. The cartilage gets worn in an active dog, and it is important to constantly replace this with things in the diet.
Sorry Bobby, but you are wrong. There is no doubt that PennHIP is the best for adults, you see not only does it tell you what to expect in the future for puppies (as you rightly point out), but it also tells you what you have now AND what to expect in the future with adults. Send any OFA x-ray to more than 5 vets and you will most likely get at least 3 different results. There are lots of scientific articals about the differences and certainty of predictions based on analyzing results from both tests, they can be found at www.pennHIP.org under the heading scientific research (http://research.vet.upenn.edu/pennhip/ScienceandResearch/Scientific...).
Here is a link from a vet that usually does OFA testing.
Sorry Bobby, but you are completely mislead, the OFA type test has been used for over 40 years. We ourselves have used it since 1975, I might add with absolutely no improvement in the results gained.
PennHIP was developed because it was felt that OFA is not good enough to predict problems. In fact all it can do it is make it visible what the vet can already hear. PennHIP on the other hand is the most modern generally accepted hip test commercialy available. It can do everything that OFA does, in fact one of the three positions the hip xray is taken in is exactly the same as the OFA position and is used for exactly the same purpose, to find and grade DJD. You see if the PennHIP does find DJD it also gives one out of 5 possible grades depending on the severity of the DJD. On top of that it can also predict whether the dog will develop DJD at a later time.
As I mentioned OFA type tests have never improved any hips from our breedings, however when we switched to PennHIP 10 years ago (PennHIP was so new then that there were only 6 Boerboels tested in the whole world, today there are 933 Boerboels tested), the change in the results came rapidly. Our average PennHIP score was 0,68 now it is 0,41 (from a status 2 days ago). The majority of the best results in the world come from our dogs (most of the top 10 scores). Now that is what I call improvement. In fact we even give a 6 year guarantee.
Anybody hear can submit the same OFA xray to different vets and WILL get different results, any breeder cannot use that sort of sloppyness for anything else than switching vets until the right vet gives the wanted result. Fine on paper, but completely useless in serious breeding programs.
Sorry Bobby, let me correct a couple of more things that you misunderstand. Firstly the numbers are not in any way controlled by the vet taking the x-ray. The x-rays are sent to the University of Pennsylvania and all results come from them.
Secondly I have attended well over 100 PennHIP tests and never seen a vet put a vice on the dog, that is absolutely not a part of any PennHIP.
Thirdly there is no proof that OFA is in any way more accurate at predicting DJD than PennHIP, and there is proof that PennHIP is more accurate than OFA at predicting DJD.
PennHIP is a non profit organisation.
What you are implying is that if there is no notceable damage when the x-ray is taken then none will occure at a later stage. This is also incorrect, both tests make and evaluation of the hips as they look at the time the pictures are taken. Nobody knows what the future brings, PennHIP let´s the breeder know the likelyhood of something developing later.
The real difference between PennHIP and OFA is the same as the difference between someone offering a hungry man a bit of bacon (OFA), and someone offering the same man bacon and eggs (PennHIP). Of course the choice is obvious.
Just to clarify the matter, you have not bought a puppy from us.
