Shiloh Shepherds originated over half of their founders from the Shiloh kennel breeding program of GSDs which began in the 70s; 16 out of 20 of the founders contain dogs directly or indirectly from that kennel. Two of these Shiloh founders from that line had crosses from other breeds, such as flock guardian dogs and malamute. Later, some outcrosses were done to a long haired GSD/GSD derived herding stock, a white shepherd, a GSD, and a Czech wolfdog.

Like many large breeds, Shiloh shepherds are prone to bloat (GDV). They also suffer from hip dysplasia, occasional panosteitis. Exocrine pancreatic insufficiency is also a concern in Shiloh shepherds.
The currently tested population of Shiloh Shepherds is in Hardy Weinburg equililbrium or close to it, which means breeders are doing a good job not inbreeding at present.
Genetic analysis of the breed shows that dogs from different regions fall within the same breed, but with some different genetics developing in different regions of the world. United States based Shilohs appear to have genetics that compare to dogs worldwide, while other regions appear to be becoming genetically distinct. This breed has thus far been found to have very low levels of average alleles of 4.33 and also low effective alleles of only 2.63. This indicates a severe bottleneck likely due to low number of founders for the breed.

The 86 Shiloh Shepherds in this study possessed only seven DLA class I and five DLA class II haplotypes. This is the lowest number of DLA class I and II haplotypes identified in any other breed to date and is a reflection of the small number of founders that contribute to DLA diversity in contemporary Shiloh Shepherds. However, further study and testing of Shiloh Shepherds may find more DLA types over time. Three DLA class I (1052, 1065, 1165) and II haplotypes (2017, 2053, 2080) are found in 88% (DLA class I) and 93% (DLA class II) individuals.
The follow includes dogs with birthdates listed in the database.
DLA Haplotypes in the Breed
The Dog Leukocyte Antigen or DLA is the region in the canine genome that controls the immune system, among other things. There are three classes or areas, and the VGL Canine Diversity Test genotypes or records the two regions with the most variation. Because it is an area that mutates more rapidly than others, the method VGL uses is ideal for identifying specific combinations of DNA, and not merely showing whether a dog inherited two of the same sets of genetics from its parents or two different ones.
"Haplotype" is a generic name for a set of genes that are bound together and inherited as a set. The DLA Class I and Class II haplotypes are very tightly bound and represent about 2 million base pairs of DNA - a sizeable chunk. These two haplotypes together make an extended haplotype that is nearly always passed from parent to puppies as a pair. We therefore have two tables below showing both the combinations of DLA found in this breed and how often they appear, and also how often they appear individually.
Remember that frequency percentages do not show how many dogs carry them, but rather how many of these haplotypes exist in the breed as a whole. Every dog has two sets of DLA haplotypes, one inherited from dam, and one inherited from sire. These almost never recombine in new generations.
