Little Dipper

Little Dipper is one of Dottie and Dipstick's puppies together with Oddball and Domino. His spots are immaculately patterned to the constellation "Little Dipper," thus  him his name (this is not official, though, and he's claimed to be named this since he has similar spots to his father's, as well as a black tip on his tail). He also has a blue collar (both in cartoon and live-action) like his father, Dipstick, and his brother, Domino.
