A black Lab is a Labrador Retriever in the breed's original color, not a separate breed. Labs descend from Newfoundland's St. John's water dogs and were refined in Britain as gun dogs, which explains the dense, water-resistant double coat, the otter tail and the endless love of fetch. Adults typically weigh 55 to 80 pounds, and some carry a small white spot on the chest.
In West Palm Beach, that history shows up in small ways. A coat built for cold water sheds steadily in the heat, so regular brushing matters. Labs are food-motivated and eager to please, which makes training easier and weight gain easier too. Dogs vary: field-bred Labs often have more drive than show-bred ones, and a Lab's age and background say more than its color. Adolescents can stay bouncy for a couple of years.
