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.

In 2014, the UK breed survey reported an average lifespan for the Labrador Retriever of 12 years and 3 months, with some living up to 19 years of age. A Royal Veterinary College study, and one conducted by The University of Sydney, have concluded that Chocolate Labradors have a shorter average life expectancy than other colours of Labrador (by about 10%) and are more likely to suffer some health problems.
