Dylan is the main male character and main protagonist of 101 Dalmatian Street of the 101 Dalmatians franchises.
He is the eldest sibling and eldest male puppy of the Dalmatian family, son of Delilah, the older brother/half-brother of Delilah's other puppies, the stepson of Doug, the stepbrother of Dolly and her siblings and great-great-great grandson of Pongo and Perdita.
He is voiced by Josh Brener, who currently voices Donatello in Rise of the Teenage Mutant Ninja Turtles.
In the series, Dylan along with his stepsister Dolly, is tasked by his mother Delilah and stepfather Doug to look after their 97 younger siblings whilst they go out to work.
In the episode "Who The Dog Do You Think You Are", Dylan comes across a painting in his attic called The Prince of Dalmacia which appears to resemble him wearing a crown. This makes the other puppies (sans Dolly) think that Dylan has descended from royalty. Hearing this, the Dalmatians' neighbour Clarissa the Corgi tricks Dylan into marrying her in order to become royalty too. However at the end of the episode, Dylan and Dolly discover that the painting was not of a Dalmatian but a different breed of dog which had dust on it, which made it look like a Dalmatian. Horrified that she married a "commoner", Clarissa destroys her marriage certificates. Delilah then reveals to Dylan that the painting was purchased from Camden Market from less than £10.
In the episode "A Summer to Remember", Dylan goes on holiday with his family to Cornwall where he meets a collie named Summer, who becomes his love interest. The relationship is short-lived due to Dylan having to return to London.
Dylan is the most responsible of the dalmatian siblings. He loves and protects his brothers and sisters including Dolly despite her actions and attitude. He's also more of a worrier wart and will do anything to make sure his family's safe.
Dylan has one black ear and one white ear (like his mother Delilah) and wears a red collar with a silver star tag.

Unlike his mother and his other siblings who speak with English accents, Dylan speaks with an American accent like his stepfather and stepsiblings. It is possible that the reason for this is Dylan may have a different father from his other siblings and that Dylan's father may have been American and that Dylan picked up the accent whilst his other siblings father/fathers were English.
Dylan is the great-great-great grandson of Pongo and Perdita. This would mean that Dylan's mother Delilah is the granddaughter of either Dipstick's children Domino, Oddball, Little Dipper (who are the only known grandchildren of Pongo and Perdita) or a child of one of Pongo and Perdita's other 14 puppies.
According to a presentation at Cartoons On The Bay 2019, Dylan is 12 years old in human years.
In the pilot episode, both of Dylan's ears were completely black, giving him the appearance of his great-great-great-grandfather Pongo. This was later changed to having his right ear black with white spots and his left ear white with black spots.
