Labrador Retrievers descend from the St. John's water dogs of Newfoundland, which British sportsmen refined into steady gun dogs for retrieving game from land and water. The thick otter tail, dense water-resistant double coat and strong build all come from that work. Despite the name, the breed isn't from Labrador. Black, yellow and chocolate are the recognized colors, and field-bred Labs are often leaner and more driven than show-bred ones.
Many Labs are sociable and eager to please, which is why they're so common as family and assistance dogs. They also love food, stay bouncy through a long adolescence, and shed heavily. In a compact city like Trenton, where sidewalks, neighbors and other dogs are never far away, a Lab does best with steady training, portion control and a dependable daily routine.
