Domino

Domino is one of Dottie and Dipstick's puppies together with Oddballand Little Dipper. He has two black ears with rows of white spots like a set of game dice, thus earning him the name "Domino." He also has a blue (live-action)/red (cartoon) collar that has a domino hanging from it. It is also worthy to note that Domino appears to have a lot of large black spots, as opposed to Little Dipper whose spots are more numerous and smaller.
