Cast and Characters

Joey Lawrence as Oliver: an orange orphaned kitten who is looking for a home. He joins Fagin's gang of dogs before being taken in by Jenny. He also saves her life from the black-hearted loan-shark, Sykes.
Billy Joel as Dodger, a carefree, charismatic mongrel with a mix of terrier in him. He claims to have considerable "street savoir-faire". He is the leader of Fagin's gang of dogs, and is Oliver's first acquaintance, as well as his eventual best friend and bodyguard. He is the object of Rita's affection.
Cheech Marin as Tito, a tiny yet passionate Chihuahua in Fagin's gang. He has a fiery temper for his size, and rapidly develops a crush on Georgette (although she is initially repulsed by him). His full name is Ignacio Alonso Julio Federico de Tito.
Richard Mulligan as Einstein, a gray Great Dane and a member of Fagin's gang. He is named ironically as he is not particularly bright, representing the stereotype that Great Danes are friendly but dim-witted.
Roscoe Lee Browne as Francis, a bulldog with a British accent in Fagin's gang. He appreciates art and theatre, particularly Shakespeare. He also detests anyone abbreviating his name as "Frank" or "Frankie" (which Tito frequently does).
Sheryl Lee Ralph (Ruth Pointer, singing) as Rita, an Afghan Hound[3] and the only female dog in Fagin's gang. She is street-wise and takes Oliver under her wing.
Dom DeLuise as Fagin, a lowly thief who lives on a barge with his dogs. He desperately needs money to repay his debt with Sykes. Because of his economic situation, he is forced to perform criminal acts such as pick-pocketing and petty theft, but in truth he is well-meaning and genial most of the time.
Taurean Blacque and Carl Weintraub as Roscoe and DeSoto respectively: Sykes's vicious Doberman Pinschers who have a hostile history with Dodger and his friends. Roscoe is the apparent leader, while his brother DeSoto seems to be the more savage of the two. Both of them are killed in the climax after falling onto the electric rail tracks while fighting with Dodger and Oliver. Roscoe wears a red collar and DeSoto wears one that is blue.
Robert Loggia as Sykes, a cold-hearted, immoral loan-shark and shipyard agent who lent a considerable sum of money to Fagin and expects it paid back. He is ultimately defeated at the film's climax when he indirectly drives his car into a train, killing him in the process.
Natalie Gregory (Myhanh Tran, singing) as Jennifer "Jenny" Foxworth, a kind-hearted, rich girl who adopts Oliver.
William Glover as Winston, the Foxworth family's bumbling but loyal butler.
Bette Midler as Georgette, the Foxworth family's prize-winning poodle. Vain and spoiled, she becomes jealous of Oliver but eventually accepts him and Fagin's gang. When Tito displays his attraction to her, she initially responds with revulsion. At the end, however, she displays considerable attraction to Tito, so much, in fact that she sends him running for his life when she tries to bathe, dress and groom him.
Frank Welker as Old Louie, an aggressive, bad-tempered hot dog vendor who appears early in the film when Oliver and Dodger steal his hot dogs. He is described by Dodger as "a well-known enemy of the four-legged world", meaning that he hates both cats and dogs.
