Due to their long association with humans, dogs have expanded to a large number of domestic individuals[10] and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.[11] Over the millennia, dogs became uniquely adapted to human behavior, and the human-canine bond has been a topic of frequent study.[12]

The dog has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.[13] Dog breeds vary widely in shape, size, and color. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and the military, companionship, therapy, and aiding disabled people. This influence on human society has given them the sobriquet of "man's best friend."
