A black Lab is a Labrador Retriever in the breed's original color, not a separate breed. Labs trace back to the St. John's water dogs of Newfoundland, later refined in Britain as retrieving gun dogs, which explains the dense, water-resistant double coat, the otter tail and the love of fetch and water. Adults generally weigh 55 to 80 pounds.
In Jersey City, that size matters in a walk-up or a tower with a shared elevator, while the sociable temperament helps with neighbors and other dogs at the dog runs. Color doesn't change personality, and Labs vary in energy, so a leaner, more driven Lab needs more activity than a mellow one. Plan on daily exercise, consistent training, measured meals and plenty of brushing during seasonal shedding.
