A black Labrador Retriever is a Lab in the breed's original and often most familiar color, not a separate breed. The earliest Labs, descended from the St. John's water dogs of Newfoundland and refined by British sportsmen into gun dogs, were mostly black, and black remains genetically dominant over chocolate. Black Labs share the breed's otter tail, broad head, dense water-resistant double coat and strong, athletic frame, sometimes with a small white chest spot.
Color does not change personality, so a black Lab tends to be the same friendly, food-motivated and eager-to-please companion as any other Lab. Field-bred dogs are often leaner and more driven than show-bred ones. Expect a dog that needs daily exercise, consistent training, careful portions and plenty of brushing during shedding season, and that matures slowly through a bouncy adolescence.
