Labrador Retrievers have proven to have a high success rate at becoming guide dogs. A study was recently done on how well four different breeds (Labrador Retriever, Golden Retriever, Labrador Retriever/Golden Retriever Mix, and German Shepherds) trained to become guide dogs. In this experiment, German Shepherds had the highest chance of not completing it. Labrador Retrievers and Labrador Retriever/Golden Retriever Mix had the highest success rate. However, German Shepherds and Golden Retrievers had a higher success rate after going through longer training than the training required for Labrador Retrievers.
