Dog owners tell their vets that Labrador retrievers are always interested in food, and new work shows there might be a biological truth to the claim. A May 3 study in Cell Metabolism links a gene alteration specifically found in Labs and related flat coat retrievers to greater food-motivated behavior, describing the first gene associated with canine obesity. The variation also occurs more frequently in Labradors chosen as assistance dogs, and might explain why these canines seem more trainable with food rewards.
