StoryJim Dear gives his wife Darling a cocker spaniel puppy called Lady. Lady enjoys a happy life with the couple and with a pair of dogs from the neighborhood, Jock and a Trusty. Meanwhile, Tramp, lives life from moment to moment, be it begging for scraps from an Italian restaurant or protecting his fellow strays Peg and Bull from the local dog catcher. Lady is saddened after Jim Dear and Darling begin treating her rather coldly. Jock and Trusty take an immediate dislike to Tramp. Jim Dear and Darling decide to go on a trip together, leaving their Aunt Sarah to look after the baby and the house. When Lady clashes with Aunt Sarah's two Siamese cats, Si and Am, she takes Lady to a pet shop to get a muzzle. Lady escapes, but is pursued by some street dogs. Tramp sees the chase and rescues Lady. The two then visit a zoo. That night, Tramp shows Lady how he lives, culminating in a candlelit Italian dinner. Lady and the Tramp share a spaghetti. As Tramp escorts Lady back home, he stirs up trouble in a chicken coop. When the two dogs flee, Lady is caught by the dog-catcher. At the pound, the other dogs admire Lady's license. Soon the dogs reveal the Tramp's many girlfriends. Eventually, Lady is collected by Aunt Sarah, who chains Lady to a doghouse in the back yard. Jock and Trusty visit to comfort her, but when the Tramp arrives to apologize, thunder starts to rumble as Lady furiously confronts him, after which the Tramp sadly leaves. Lady sees a rat trying to sneak into the yard. Lady barks frantically, but Aunt Sarah yells at her to be quiet. The Tramp hears her and runs back to help. Tramp enters the house and finds the rat in the nursery. Lady breaks free and races to the nursery to find the rat on the baby's crib. Tramp kills the rat, but when Aunt Sarah comes to the baby's aid, she sees the two dogs and thinks they are responsible. She pushes Tramp into a closet and Lady into the basement, then calls the pound to take the Tramp away. Jim Dear and Darling return as the dogcatcher departs. They release Lady, who leads them to the dead rat, vindicating Tramp. Jock and Trusty, having overheard everything, chase after the dogcatcher's wagon. Jock is convinced Trusty has long since lost his sense of smell. They bark at the horses. Jim Dear arrives by car with Lady, and Lady is happily reunited with the Tramp before they discover that the wagon fell on Trusty. Tramp, now a part of Lady's family, has his own collar and license. Lady and the Tramp also have their own family, a litter of four puppies.

The laugh of the Hyena in the zoo is repeatedly used in several Crash Bandicoot video games for the "voice" of the character Ripper Roo.
The mischievous young puppy at the end of the film (the one who resembles his father, Tramp) is called "Scamp". He was featured in a children's book, a syndicated daily comic strip, and, in 2001, his own direct-to-video film.
Before animating the fight between Tramp and the rat, animator Wolfgang Reitherman kept rats in a cage next to his desk to study their actions.
The twin Siamese cats known as Si and Am they were then named Nip and Tuck.
The decision to film in Cinemascope was made when the film was already in production, so many background paintings had to be extended to fit the new format. Overlays were often added to cover up the seams of the extensions.
To maintain a dog's perspective, Darling and Jim Dear's faces are rarely seen. As the release date neared, Walt Disney was dismayed to learn that not all theaters were equipped to show a film in CinemaScope.
Walt Disney originally didn't want to include the 'Bella Note' spaghetti-eating scene, now one of the most iconic moments in the whole Disney canon.
