Delilah Dalmatian is a British female Dalmatian dog and one of the main characters of 101 Dalmatian Street. She is the great-great granddaughter of Pongo and Perdita. She's married to Doug, and together they have 99 puppies from previous marriages, including Dylan and Dolly. She is a nurse and can diagnose by scent.
Delilah has white fur with black spots, but much like her son Dylan, one of her ears is black with white spots. She also wears a purple and green collar with a rectangular shape attached to it.
It's revealed that Delilah is the biological mother of Dylan, making it possible she was widowed before marriage and the step-mother of Dolly, despite the latter calling her mom.
She’s the first non-protagonist dalmatian that is the user of the World Wide Woof.
