Labrador Retrievers descend from the St. John's water dogs of Newfoundland, which British sportsmen imported in the nineteenth century and refined into a steady gun dog for retrieving shot game from land and water. That working purpose still shows in the breed's thick otter tail, dense water-resistant double coat, strong build and remarkable food motivation. 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, which explains their long run as one of America's favorite family dogs and their wide use as guide and assistance dogs. That enthusiasm comes with real needs: daily exercise, consistent training, careful portion control and patience through a long, bouncy adolescence that can last until two or three years old.
