    Default SD2 - Skeletal Dysplasia (2) in the Labrador Retriever - NEW Finding

    The SD2 that is now identified is a distinctly different genetic disorder from the Retinal dyplasia with skeletal deformity (dwarfism) RD/OSD, which by screening breeding stock and early eye exams for puppies and selective breeding, there been a reduced prevalence in field trial lineage. This appears to be a milder form from the article below.

    Thanks for posting. Interesting, I wonder if this gene is why some show bred labs have big bodies on short legs.

    Affected dogs have slightly shorter legs but according to our knowledge no other health problems...
    Seems like the genetic tests are stating to scratch the bottom of the barrel. If breeders select for a trait, like shorter legs, then obviously there is a gene or genes involved in that trait. If it is not a health risk/issue, then it comes to interpreting the breed standard as to whether that is a trait that ought to be bred for or not. (Not advocating for overdone show Labs...nor lanky specimens either).

    Perhaps the next genetic test will find the "disease" that is allowing Field Trial Labs to see clearer are greater distances than a dog should be able to, or perhaps the gene that makes some Labs breathe fire and other not. It all seems like a little overkill to me... geneticists looking for the next best thing to convince Labrador owners they need to test for. Tests like this generally result in one thing, lined pockets.

    Well, there is no commercial test yet. It would be nice if those researchers were looking for the gene(s) that cause epilepsy or tricuspid valve dysplasia instead of short legs, but it is still interesting.

    Show breeders are in fact breeding for a certain look...it does not take but 1-2 generations to modify how a breed of dog may look. Dwarfism is most evident in the Dachshund...a true dwarf without medical issues...

    And I could change my mind and regret it.

    This has already shown up on facebook and a blog tonight. I came here looking to see if it had arrived. The sound you hear in the background is corn. Popping.

    Yeah, but what I was wondering was if this is the gene that gets them that look.
