A black Lab is simply a Labrador Retriever in the breed's original color. The earliest Labs, descended from Newfoundland's St. John's water dogs and refined in Britain as gun dogs, were mostly black. Adults typically weigh 55 to 80 pounds and have a broad head, an otter-like tail and a dense, water-resistant double coat, sometimes with a small white chest spot.
Color doesn't change personality. Black Labs are generally friendly, food-motivated and eager to please, though leaner, field-bred dogs can be more driven than show-bred ones. In Cranston, that means a dog who'll enjoy leashed trail walks and a snowy yard, but who needs consistent training, measured portions and plenty of brushing through the shedding seasons. Adolescence can run long and bouncy, so patience pays off.
