What is the history of selective breeding guide dogs?

The aim was to train dogs to assist visually impaired individuals, focusing on temperament, intelligence, and trainability. Over the years, breeds such as Labrador Retrievers and Golden Retrievers became popular choices due to their friendly nature and adaptability. Today, various organizations continue to refine breeding practices to produce guide dogs that Excel in their roles.
