As this collection of dog pictures illustrates, the Lab is a uniquely beautiful animal. Warm and intelligent, the Lab is America's number one breed registered with the American Kennel Club. Even non-dog people can recognize a Lab, and artists and photographers have captured his image countless times -- usually as the loyal companion, waiting patiently by his owner's side.

Built for sport, this dog is muscular and athletic, as can be seen in these pictures of Labrador Retrievers. He has a short, easy-care coat, a friendly demeanor, keen intelligence, and plenty of energy. Devotion to this breed runs deep; Labs are loving, people-oriented dogs who live to serve their families, and owners and fans sometimes liken their Labs to angels.

The breed originated on the island of Newfoundland, off the northeastern Atlantic coast of Canada. Originally called the St. John's dog, after the capital city of Newfoundland, he was bred to help the local fishermen – hauling nets, fetching ropes, and retrieving fish that had escaped the nets – as well as to be a family dog.

Today, most Labs skip the hard labor and spend their days being pampered and loved by their people. However, some Labrador Retrievers still serve as indispensable working dogs.
