Stats comparison between Show and Working Lines - Page 1

Hello boys & girls,

Does anyone have any official stats regarding a comparison of the stats of hip / elbow dysplasia between show and working GSD lines?

there would not be enough generations of hip scored dogs that could be called pure show or working and the mathematical sensitivity to what actual dogs/ lines were sampled would make any survey an exercise in sample bias fallacy and totally invalid.

 

sorry you will have to do the hard work yourself and check the specific lines of interest in great detail.

Currently there are about 90,000 GSD in the OFA  Hip database alone.

One could look at those dogs one at a time and try to figure out their bloodlines based only on their names. When you select a dog you are interested in, you can click on the names and, if you're lucky, see a pedigree. Good luck, it will take years. 

33,000+ GSD's with elbow evaluations.

It is quite interesting though, that SV (or any other body) that looks into similar issues about health, has not conducted any comparison of that kind so that any useful conclusions come up....and finally have an idea if the design they decided to give to the contemporary show lines has affected its health or not....

Instead, I hear a lot of comparisons to other breeds with greater dysplasia issues (mainly large - giant breeds) that are made to support the conclusion that "it is not the anatomy that decides dysplasia". Yet, when SV admits that -to an extent- dysplasia is acquired isn't that an indication that the anatomy comparison among lines within the same breed should be one aspect that would be well worth investigating?

What would be simpler to do if not to compare the 2 main different bloodlines that include the difference in anatomy????

 

What about all the dogs who are of mixed ancestry? And what year do we decide the dogs are now "showline" since at one time they were simply "German Shepherds"? 

If I am paid I can write a computer program code set that will process all this data.

I don't believe the SV, or any GSD registry, officially sees 'two separate bloodlines. My dogs paperwork does not have a classification of 'Working' / 'Show' line dog, does yours? 

 

actually the SV has addressed that repeatedly and in reasonable detail given the categorization complexities. stats have been made available a multiple times in the SV magazine over the past decade or so and the last major update i know of was 01/24/2015 by Quoll at the werther meeting when he reviewed the intermittent results of the gelenkstudie. ditto for spine/ces issues and numbers. all this info is available to SV members; to morally bankrupt troll's misrepresenting raiser's work and spirit, not so much.
