Jewel was one of the original fifteen puppies in the movie, and the second to be refered to by name. Her name comes from how the spots around her neck resemble a jeweled necklace. She and her siblings were kidnapped by Horace and Jasper for Cruella to make them into a fur coat. With the help of her family, she escapes them along with her siblings.
In most of the tie-in merchandise, such as toys and books, she is very girly in character, contrasting Two-Tone's tomboyishness. She has been shown to be a bit annoyed at Whizzer's antics as well.
