Dottie is mate to Dipstick and mother to Oddball, Little Dipper, and Domino. Her owner is named Chloe Simon.
She is more of a minor character in this story, but she is a very caring and is very close to her family, even in troubled times when she gets kidnapped by Cruella.
Dottie also appears in the video game: 102 Dalmatians: Puppies to the Rescue. Though she has only a minor role in that as well, and only warns Oddball and Domino not to go near Cruella, but the two pups ignore her orders and go to rescue their siblings anyway.
Dottie can be shown wearing either a red or purple collar, and have a pink or black nose.
