The objectives of this study were the description of changes in genetic diversity in a colony of dog guides since its founding, and the investigation of the genetics of longevity in that population. Two breeds of dog, German Shepherds (GS) and Labrador Retrievers (LR), were evaluated. There were rapid increases in average pairwise relationship in both breeds, although the average was approximately one-third higher in the GS population than in the LR population. A similar trend was observed for average inbreeding. In the current generation, relationship and inbreeding for all animals averaged 25.3% and 26.2% in GS and 15.5% and …
