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 sturdy 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.
Many Labs are sociable, eager to please and keen on anything involving people, balls or water. In Ames, that usually means they enjoy the trails and the college-town bustle, but they still need real daily exercise, consistent training and careful portions. Expect a bouncy adolescence that can last until two or three years old, and plenty of shed hair on the couch. Dogs vary, so a Lab's age, history and energy matter as much as the breed.
