    Default How many people are testing for PRA in the Labradors?

    I know PRA is very prevalent in many other breeds and PRA genetics test is imperative. I check many postings for litters for sale and they list all the clearances done and rarely is the genetics test for PRA done. Is it extremely rare in the Labrador or is this something we need to be checking more vigilantly?

    It is not rare, though I can only speak for show lines. We can easily breed around it and there are plenty of carriers in the breed. I haven't seen an affected in years. I am curious, are their pedigrees in the field lines that have PRA?

    I have tested several of my dogs for PRA and RD. Everyone clear. I do see carriers when I am looking at potential stud dogs.

    Might set this up as a poll... I'd be interested in the result... I've never tested any dogs for it, used to be a at-risk type test; which was very interpretive.I believe that has changed. Still the disease itself can have many causes only a couple of which are testable genetically. Most of the individuals in the lines I look at; could mark a bird just as good @ 14yrs. as they could at 2, and were still rearing to go get them. i've never seen an individual with the condition. On the other hand I know that EIC & CNM have been found in those same lines, have seen pups accidentally produced with it before they had a test. So testing for those are more important to me, I'm sure it depends on individual priorities, and what a particular breeder is comfortable with.

    I have field Labs and at one point believed that PRA was not found among field dogs. However, a vet-student client tested her puppy for everything under the sun for practice and discovered hers was a PRA carrier, much to my horror- both my bitch and the stud dog were tested and my bitch proved to be a carrier. I tested all of my dogs and the only other carrier was a sister to this bitch. However, I now routinely test as part of my pre-breeding ritual and still have some carrier descendants of those two, which are of course only bred to clear dogs.
    I know of other PRA carrier field bred dogs and because it seems possible that it is more wide-spread than we realize, I would not personally buy a puppy unless at least one of the parents had been tested clear.

    p.s. optigen PRA testing does not void the necessity to perform annual CERF exams....

    I test for PRA, but I also do many, many other tests. I think tests are a great way to be able to continue breeding certain pedigrees while being able to avoid producing preventable diseases.

    I test.
    Anyone who has show dogs in the pedigree needs to test. Anyone who has British field trial dogs needs to test. American field trial dogs should test ( in my opinion) .
    However, I had a very nice girl who is now 10 yrs old. Her father tested clear and I did not test her mother because of the father being clear. Unfortunately Optigen made a human mistake and the father was a carrier and my girl is now blind.( as well as several other dogs around the country) This was AFTER the original test that was not reliable. So even if you test shite still happens, it happened to me and unfortunately ,the litter I produced.

    All of our dogs are tested, 3 males and two females. Our males come from similar lines and they aren't show lines. One of our dogs is a carrier and I wouldn't hesitate to breed him; I would test the entire litter once on the ground to determine clear/carrier pups and inform the owners of the pups status as carrier/clear. Our dogs were tested through Optigen, the PRA is not a cheap test, none of the DNA based tests seem to be anyway. As stated in an earlier post, it doesn't replace the annual CERF exam.

    Bridget,

    How unfortunate! You did all that you could to prevent PRA and still ended up with it! Was there any potential for legal reparations?

    I've tested my dogs for prdc-PRA and still get annual eye exams for my breeding stock. I trust those tests are valid and accurate.
