The domestic dog was the first species to be domesticated and has been selectively bred over millennia. Dogs vary widely in shape, size and colors. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and military, companionship and aiding disabled people and therapeutic roles. This influence on human society has given them the sobriquet of "man's best friend".
