Labrador Retrievers descend from the St. John's water dogs of Newfoundland, which British sportsmen refined in the nineteenth century into a steady gun dog for retrieving game from land and water. The thick otter tail, dense water-resistant double coat and strong build all come from that work. Labs come in black, yellow and chocolate, and field-bred dogs are often leaner and more driven than show-bred ones.
Many Labs are sociable, eager to please and keen on anything involving people, balls or water. That enthusiasm comes with real needs: daily exercise, consistent training and careful portion control. Expect a long, bouncy adolescence that can last until two or three years old, and plenty of shed hair, especially when the coat turns over with the seasons. A Lab's own history and personality matter more than the breed label.
