It was Disney’s first animated film set in a contemporary, real-world time period instead of distant lands or fantasy worlds.

The film is loosely based on a magazine story by Ward Greene called Happy Dan, the Whistling Dog.

Lady’s full breed is an American Cocker Spaniel, which was an extremely popular dog breed in the United States at the time.

Tramp is a mixed-breed mutt with no official name for most of the movie, though fan theories suggest he is a terrier and schnauzer mix.

Early drafts called Tramp “Homer” and “Rags.” Walt Disney chose the final name himself.

The iconic spaghetti scene was inspired by a romantic live-action reference shoot with real dogs. This scene popularized the idea of pets eating Italian food in movies.

Peg the dog is voiced by the famous singer Peggy Lee, a towering figure in jazz and pop music. Peggy Lee also voiced Darling, Si, and Am.

Si and Am’s song was one of Disney’s most controversial tunes due to its negative cultural stereotypes of Asians.

The film was Disney’s first widescreen CinemaScope animated movie. Because of CinemaScope, Disney had to redesign their storyboards to use wider framing.

The dog catcher’s wagon was designed to feel claustrophobic and terrifying from a dog’s perspective.

The rat fight scene was added late in production to give Tramp a heroic moment.

The film was a major box office success and helped Disney Animation financially. It also helped partly fund the creation of Disneyland in California.

It was one of the first Disney films released on VHS in 1987.

The original story idea ended with Tramp remaining a stray instead of settling down.

The song “Bella Notte” translates to “Beautiful Night” in Italian.
