A black Lab is a Labrador Retriever in the breed's original color, not a separate breed. Labs descend from the St. John's water dogs of Newfoundland and were refined in Britain as gun dogs, which explains the dense, water-resistant double coat, otter tail and athletic build. Adults weigh 55 to 80 pounds, and some have a small white chest spot.
Color doesn't change personality. Black Labs tend to be friendly, food-motivated and eager to please, and they mature slowly, with a bouncy adolescence that can last into the third year. In Bayamon, expect to plan around daily exercise, consistent training, measured portions and heat, since the double coat sheds year-round and a dark coat warms quickly in the sun. Each dog varies, so age, energy and history matter more than breed reputation.
