The black Labrador Retriever is a Lab 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 otter tail, broad head and dense, water-resistant double coat. Adults usually weigh 55 to 80 pounds.
Color doesn't change personality. Black Labs are typically friendly, eager to please and driven by food, though field-bred dogs tend to be leaner and more intense than show-bred ones. In Champaign, that build suits a household that walks daily on park paths and can live with hair on the furniture. They mature slowly, so expect a bouncy adolescence, consistent training, careful portions and plenty of brushing when the coat sheds.
