    Default PennHip - Understanding Results?

    Okay I got Ranger's PennHip results but it makes no sense to me - can some one explain what I'm looking at....

    Both hips will be scored.

    Ideal would be upper 20 percentile in both.
    Upper 40% in both is good.

    I read where that when a dog had hip issues, it is on the left side most of the time.

    Labs are rated against a lab database.

    Okay what do the numbers mean on the form?

    How do you know what precentile? I see the DI index....does it mean anything?

    The laxity profile puts him in the 80th.....but does it go any more specific ranking? Or just in 10% groupings?

    The lower the DI, the better. The DI's are more important than percentile because the percentile ranking is constantly changing if I remember right. IOW, labs that started out at the 90th percentile back when PH started may only be at the 60th or less now that they've got more data.

    I think the lowest DIs for labs was about 0.19 a year or so ago and that was a field dog. Anyone have the current data? I'm thinking 0.3 is not too shabby still. I really wish PH would have a database online.

    I wish I had my report here from the Lab I gave away. He was the bottom 20% on the left and bottom 40% on the right.

    I seem to remember a 62 on the right, which was not good.

    I seem to remember that most of it is explained on the report. Maybe they didn't send you that info. The D1 index is how your dog's hip compare to other Labs.

    Anne, jump in here cause I know you can put it in better tech terms.

    "There is an increasing risk of developing DJD as the DI increases; low risk when the DI is close to 0.30, high risk when DI is close to 0.70 or above."

    Rangers is 0.37 for both hips = we are looking good?! And in the 80th percentile...

    Just making sure I'm reading the report correctly - this is only the 2nd dog I had PennHip and the results for the first dog went directly to Aussie (aka Julie) and I never got to see his........so if I'm looking at this correctly, we should not be stressing about Ranger's hips....

    FOM,

    If you have a few moments, go into the Labradata.org database, click on Certification Search, and then find the Pennsylvania Hip Improvement Program and hit Search. There are several dogs entered w/ PH numbers.
    It appears, based on the most recent PH submissions to Labradata, that the mean DI for labs right now is ~.46.

    You can then click on a dog, click on Certs/Tests, and then "View Doc" and you'll see how that Percentile ranking relates to the DI in general. Your .37 seems to be great based on what I see! Several dogs that scored in that range were also OFAd and came back Excellent (I think one Good).

    I noticed one dog's DI was .6 or so (w/no DJD present), and the dog had a corresponding "Fair" rating by OFA. It's all pretty interesting!

    ETA: My instructions may be meaningless if the database is changed a lot after tonight's updates as announced by Maureen earlier!

    A DI of 0.3 or smaller is pretty much the gold standard since, at that level, there is virtually no chance that a dog will ever develop dysplasia. With both hips at 0.3, the dog would basically be in the 90th percentile (best 10%) or better. With DI of 0.5 or less, the dog will be in about the top 50% of Labs. PennHIP uses that as its standard for breeding, arguing that if only better than average dogs are bred, hips will continue to improve over time.

    I disagree. That logic would exclude many dogs that would be the equivalent of OFA Good and essentially every dog that would be rated Fair. While that may make mathematical sense, it disregards the other qualities that need to be considered in making breeding decisions. I also wonder how much, if any, research has been done on whether or not there is a level at which hips are too tight in a manner that might contribute to other injuries.
