Labrador Retrievers trace back to 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 job. Labs come in black, yellow and chocolate, and field-bred dogs tend to be leaner and more driven than show-bred ones.
Most Labs are sociable, eager to please and happiest around people, balls or water, which is why they're so common as family and assistance dogs. In State College, that sociable streak suits a town full of walkers, but the coat takes work: shedding is heavy, especially in spring and fall, and a long, bouncy adolescence can last until two or three years old. Plan on daily exercise, consistent training and careful portions.
