DNA TESTING, Parentage

Matching parentage DNA on all breeding stock is essential so the Shiloh Shepherd gene pool remains true and verified. This is the Parentage/Genetic Marker Test, which is not be be confused with the Canine Genetic Diversity Test also offered by UC Davis Veterinary Genetics Laboratory. Same company, different tests. In order complete the Parentage/Genetic Marker Test you will need to provide the DNA number for your dog’s sire and dam. If you need help with this, please contact us here at the Shiloh Shepherd Resource Center.

  • Parentage DNA is required for several of the Shiloh Shepherd registries (NSBR, TSSR, & WSSBA)
  • UC Davis maintains the largest collection of Shiloh Shepherd DNA samples (over the course of 17+ years), thus are easily able to match parentage when provided with the sire/dam DNA numbers.
  • DNA kits available to ALL Shiloh Shepherd owners, regardless of where they will be registering their dogs. [ORDER TODAY!!!]

DNA, Embark (Breed & Health Test)

While this test helps with DNA health testing (i.e. DM testing, etc.), it DOES NOT determine parentage. 

“An Embark Breed + Health dog DNA test enables a dog owner to learn about their pup’s breed, ancestry, health, relatives, and more with a simple cheek swab. With a research-grade DNA genotyping platform, Embark looks at over 350 breeds and more than 175 genetic health conditions and traits. You can discover and connect with dogs that share DNA with yours with the world’s only canine relative finder, free with purchase. The most accurate & highest rated dog DNA kit on the market. ”

DNA, Canine Genetic Diversity

Genetic Diversity Testing for ISSA Shiloh Shepherds {https://vgl.ucdavis.edu/services/dog/GeneticDiversityInShilohShepherd.php}

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 assess 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.

Genetic diversity testing of Shiloh Shepherds is now in the preliminary results phase. During this phase, we continue to test more registered dogs to build genetic data necessary to provide breeders with an accurate assessment of genetic diversity in their breed. This report is based on testing of 86 Shiloh Shepherds from North America and Europe. Allele and DLA haplotype frequencies are updated based on the current population of dogs tested.

This study is sponsored by the ISSA Shiloh registry and concentrates primarily on their breeding stock.

  • Part 3 (and last) gives an idea of “What’s Ahead” and discuss the whether orthopedic disorders such as HD inherited, the variation in polygenic traits, the random nature of polygenic disorders and how much is genetic and how much environmental. {http://devinefarm.net/rp/gen3.htm}
