Roscoe and DeSoto are two Dobermans belonging to Bill Sykes who appear as the secondary antagonists in the Disney's 1988 movie, Oliver & Company. Roscoe and DeSoto wear a studded red collar and blue collar respectively.
Both dogs speak with a soft Italian accent, in reference of the Italian Mafia.
They both come off as smooth-talking, mobster-like goons who don't mind playing with their victims. But they can also be violent, vicious, brutal, ruthless, thuggish, mean, and downright merciless. This also plays on the stereotype of Dobermans being savage, brutal, and used often as attack or guard dogs.
Roscoe appears to be attracted to Rita, as he tells her in the film, "You know, Rita, I can't figure out why you'd rather hang around a dump like this, when you could be living uptown with a class act like myself." but she is plainly disgusted by him.
Roscoe seemed to be the more cool-headed of the two, while DeSoto is a bit more vicious, shown when DeSoto displayed a desire to eat Oliver (failed), while Roscoe thought it would be better to heed their master, Sykes' call. Also, at the end of the film, while Roscoe simply falls off the back of Sykes' car to his death after accidentally tearing off Dodger's bandanna, DeSoto actually had to be fought off by Oliver in order for him to die.
In the movie, Bill Sykes (who lent Fagin some money) comes by Fagin's home to get his money back from him and he sends his two dogs, Roscoe and DeSoto into Fagin's boathouse to tell Fagin to meet up with his boss while they harass Dodger and the gang. Once inside, Roscoe flirts with Rita, while DeSoto sniffs around the houseboat. When Francis insults Roscoe, he loses his temper. Tito tries to fight them but is luckily held back by Einstein, who suggests he picks on somebody his own size. However, Roscoe is not intimidated by him but Dodger waltzes up to him and asks him if he's lost his sense of humor. In reply, Roscoe smashes their TV and says, "See? I find that funny." and chuckles sinisterly.
Just as further unpleasantness is about to ensue and when their master, Sykes, calls for them with his horn, DeSoto finds Oliver but Roscoe tells him to forget it and to go. Nevertheless, DeSoto tries to eat Oliver, who in return, scratches him on the nose, causing the two dogs to attack Oliver, not before Dodger and then the rest of the gang stand in and protect him. Both dogs hesitate, knowing that they can't take on the whole gang. Outside, Sykes honks his horn again outside for the dogs to return to the car and Roscoe and DeSoto leave reluctantly, with Roscoe swearing retaliation; starting with Oliver.
Later, when Fagin goes to talk to Sykes about getting his money from Oliver's owner awkwardly, Roscoe and DeSoto attack Fagin, after Sykes orders them to do so with a snap of his fingers, but Dodger leaps forward and fights the dogs, taking severe (but invisible) injuries. When Fagin tells Sykes about Oliver's owner being rich, shows him Oliver as proof, and that they're coming tonight to get the cat back properly and loudly this time, Sykes, convinced, has his dogs pull back from Dodger and tells Fagin he has 12 hours to pay him his money back as his "last chance" when feeding dog biscuits to his dogs while Fagin and Oliver come to Dodger's aid after Dodger lays injured and unconscious with severe (but invisible) injuries from the Dobermans' attack.
After Sykes kidnaps Jenny, Oliver and the gang secretly follow them to Sykes' warehouse. While Sykes ties up Jenny, he tells her not to cry while Roscoe and DeSoto pace around, growling. Then, he orders Roscoe and DeSoto to sniff around the place for intruders after hearing a noise. When Dodger and the gang sneak into the warehouse, one of the dogs, Georgette, screams because of a broken nail, alerting Roscoe and DeSoto. Later, DeSoto is the first to smell them, informing Roscoe.
Roscoe and DeSoto run into Francis, Tito, and Einstein, who were distracting and luring Sykes away while the rest help Jenny, but just as they're about to attack, Georgette pulls a blanket down on the two dogs, trapping them until Sykes comes along and frees Roscoe and DeSoto. Sykes and his dogs chase Oliver, Jenny, and the gang, who escape with the help of a crane and Tito's electric specialty then fall and land on a long slide after Sykes destroys the crane's control with an axe, through the warehouse but just as they have them cornered and Sykes is about to snap his fingers "again" to order his dogs to attack, Fagin bursts in on his scooter, after hearing a honking noise which is actually his scooter's horn, and the gang flee.
The two evil dogs chase Fagin and the gang on the street but luckily, they are able to outrun them until Sykes and his dogs give chase in his car. When Fagin drives his friends in a substation, Sykes is still able to follow them. In a tunnel, when Jenny gets knocked onto Sykes' car, Oliver jumps on and bites Sykes' hand, but Sykes tosses Oliver into the back, where Roscoe and DeSoto are. Dodger manages to jump aboard also and jumps on Roscoe who later grabs a hold of Dodger's bandanna after being thrown out of the car's back window by Dodger. The bandanna snaps and Roscoe falls onto the subway's third rail, which electrocutes him due to the friction caused between the ruined car tires and the rail tracks. DeSoto then jumps onto Dodger and is about to strangle him, but Oliver manages to jump onto DeSoto and scratch him on his nose "again," causing DeSoto to yelp in pain, jump, and fall onto the railway tracks and get electrocuted as well. Sykes is too busy chasing the gang to even notice what's happened to his dogs and shows no mercy for his dogs as he continues to chase the gang until his car runs into a train, killing him.
DeSoto appears in the song "Everybody Wants to Be a Woof" in House of Mouse. While singing in the quartet with Tito growling at him, DeSoto replies with a growl in return, thus scaring Tito off, which contradicts their encounter in the film. Later, he is seen fighting off – along with the quartet and later Pluto – Pete.

- Roscoe appears more as Dodger's archenemy while DeSoto appears more as Oliver's archenemy.
- Although both Dobermans look identical, it is unknown for a fact if they're actually related.
- Along with their master (hit by an incoming train), both Roscoe and DeSoto appear to have one of the most graphic deaths in Disney history (more so with Roscoe than DeSoto since the latter's death was only heard from off-screen).

- Roscoe and DeSoto are the first two Disney villains to be killed via electrocution (due to them being tossed out of Sykes' car and onto the subway's third rail), followed by Ursula and Jafar.
