    Overview of Genetic Testing resources on This is not a comprehensive listing - it is a starting point for finding relevant resources. Please visit the various areas of the site using the purple navigation bar and/or the Search function.




    The extent to which genes play a role shaping the health and inherited diseases in dogs and impact canine welfare cuts across all breeds and mixed breeds. The power of understanding the genetics of dogs is a subject of interest to every person, dog owner, breeder, clubs, veterinarians, researchers studying both human and canine diseases; and believe it or not, the dog and its genome even influences the country's of the world laws and services. 

    Below find a listing for a few resources on pertaining to genetics and the use of genetic tests.

            - The practical applications for using the results of these tests to improve the health of dogs
            - The dangers for the inappropriate use of genetic tests to dog health

    January 2018 ... From the AKC Gazette Jerold S. Bell, DVM. "Breeding by the Numbers." AKC Gazette. January 2018, pp 12-16.

    “A goal of all breeds is to grow and maintain a large, diverse, and healthy population.”


    Internal link: AKC Gazette-January 2018, pgs.12-16 - J.Bell - Breeding by the Numbers

    This article addresses the aspect of population size on healthy breeding in dog breeds, genetic disorders and selection. Excerpts... "In both large- and small-population breeds, genetic diversity can be lost if breeders do not utilize dogs from the breadth of the gene pool. This is most evident in the popular sire syndrome." "Health-conscious selection through breed-appropriate genetic screening of prospective breeding individuals is the most important aspect of improving and maintaining the genetic health of any breed, regardless of its population size."

    Vets urged to take a proactive role in tackling hereditary disease

    The World Small Animal Veterinary Association has called on vets to take a proactive role in tackling hereditary disease and to advise breeders on the tests available to them before they breed from their animals.  Speaking at a press briefing during BSAVA Congress 2017, Dr Cathryn Mellersh, Head of Canine Genetics at the Animal Health Trust and a member of the WSAVA Hereditary Disease Committee, also urged vets not to shy away from telling owners if they have made a bad choice to try to deter them from making the same mistake again.

    Further, "We ask vets to advise breeders to use DNA test results to avoid breeding clinically affected dogs and to reduce the frequency of mutation within a breed, over time, without damaging genetic diversity.  When selecting a test, it is important that they ensure that the test they are using is based on sound science and on the right mutation for the breed being tested.”

    Dr. Mellersh also warned vets not to advise against breeding with carriers and said that dogs should not be excluded from breeding on the basis of a single mutation that they could test for.  “The disease mutation that the DNA test is for is not the only mutation that a carrier has,” she said.  “Most dogs carry at least 50 recessive mutations so, if carriers are not bred from and only clear dogs used then there is a risk that other mutations carried by these clear dogs will increase in frequency within the breed and new inherited diseases could emerge.”


    Interactive Module

    • Its goal is for users to expose themselves to ethical questions as they relate to breeding dog welfare and use expertise from their own experience to think critically.
    • Includes numerous links to further resources, an interactive multiple choice question, and a survey on the degree to which the user is already involved in breeding dog welfare.




    Over time we hope to add to this list of resources.



    Please note Elaine Ostrander's presentation, Dog Genes Tell Surprising Tales, begins at ~12 minutes
