Labrador Retrievers descend from the St. John's water dogs of Newfoundland, which British sportsmen refined in the 1800s into gun dogs for retrieving game from land and water. The thick otter tail, dense water-resistant double coat and webbed toes all reflect that job. Labs come in black, yellow and chocolate, and field-bred dogs tend to be leaner and higher-drive than show-bred ones.
Many Labs are sociable and eager to please, which is why they're so common as family pets and assistance dogs. That friendliness suits a household that's out on the trails often. The flip side is real: daily exercise, consistent training, portion control and patience through an adolescence that can last two or three years. Shedding is moderate to heavy, and it peaks with the seasons.
