Labrador Retrievers trace back to the St. John's water dogs of Newfoundland, which British sportsmen refined into gun dogs for retrieving game from land and water. The thick otter tail, dense water-resistant double coat and webbed toes all come from that job. Labs come in black, yellow and chocolate, and field-bred dogs are often leaner and more driven than show-bred ones.
Many Labs are friendly, eager to please and happiest around people, balls or water. That enthusiasm comes with needs: daily exercise, consistent training, measured meals and patience through an adolescence that can last until two or three years old. In a city with long winters, the dense coat is an asset, though the shedding that follows is real.
