Here are all the facts again: The Labrador Retriever is a dog breed rooted in Canada. Labs have drop ears and a black, yellow or chocolate coat. Their eyes impart intelligence and good temperament, their tail is often compared to that of an otter and their compact, round paws to those of cats. Labradors who lack nose pigmentation are called Dudley. The dogs are passionate swimmers and have proved valuable for rescuing people buried alive.
