The Labrador retriever is the world’s most popular dog, loved for their mellow and friendly temperament. They are gentle with children, so gentle that the Labrador can carry an egg in its mouth without breaking it. A really useful dog, Labradors are often used for guiding the blind and for retrieving game. Vladimir Putin has a black Labrador called Koni. Buddy, the Clinton’s chocolate Labrador, was tragically run over before he had time to write his White House memoirs.
