Labrador Retrievers descend from 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 tend to be leaner and higher-drive than show-bred ones, though both are the same breed.
Many Labs are sociable and eager to please, which is why they're so common as family pets and assistance dogs. In Concord, that sociable streak pairs well with greenways and backyards, but it comes with daily exercise, consistent training and careful portion control. Expect a bouncy adolescence that can last until two or three years old, and plenty of shed hair, heavier in spring and fall.
