Greater Swiss Mountain Dog – Sponsored Genetic Diversity Test


This research test has been generously subsidized by the Greater Swiss Mountain Dog Club of America.  For the research phase, we request that entry be limited to those that have been pre approved by the GSMDCA Health Committee, so please have your assigned GSMD entry number available for input.  If you have yet to receive a GSMD entry number please contact  It is hoped that the pre approval process will provide GSMDs from the widest range of pedigree lines as possible.  Additional entry will be available after the initial research phase sampling is complete.

The world’s best Canine Genetic Diversity Test, from UC Davis’ renowned Veterinary Genetics Lab. Developed by dedicated veterinarians and conservation geneticists specifically to assess genetic diversity in breeds, dogs, and matings.

Individual test results will not be available until after the initial breed analysis, which will be after 30 to 50 dogs, depending on the overall variation found in the breed. After that analysis is released, all test results will be sent to owners and run through the BetterBred conservation genetics algorithms.

After the initial breed analysis, results will be emailed to you from the UC Davis Veterinary Genetics Lab 5-10 days after receipt at the lab.  Results will also be run through BetterBred algorithms at that time and available for public viewing.



The Veterinary Genetics Laboratory (VGL), in collaboration with Dr. Niels C. Pedersen and staff, has developed a panel of short tandem repeat (STR) markers that will determine genetic diversity across the genome and in the Dog Leukocyte Antigen (DLA) class I and II regions. This test panel will be useful to breeders who wish to track and increase genetic diversity of their breed as a long term goal.

Short tandem repeat (STR) loci: A total of 33 STR loci from across the genome were used to gauge genetic diversity within an individual and across the breed. The alleles inherited from each parent are displayed graphically to highlight heterozygosity. DLA haplotypes: STR loci linked to the DLA class I and II genes were used to identify genetic differences in regions regulating immune responses and self/non-self recognition. Problems with self/non-self recognition, along with non-genetic factors in the environment, are responsible for autoimmune disease. Internal Relatedness: The IR value is a measure of genetic diversity within an individual that takes into consideration both heterozygosity of alleles at each STR loci and their relative frequency in the population. By ordering through the site, you give permission to to upload your results in their database. All sponsored test results will be public as a condition of sponsorship. Test results are neither good nor bad – they are merely descriptive.
