Tramp was Actually a Young Lady.
While Lady and the Tramp contains a number of iconic characters and scenes, few people are aware that Tramp was inspired by a real-life dog named Tramp.In the film, the character of Tramp was inspired by a genuine stray dog that was discovered by one of the narrative artists.
Eventually, after a lengthy search, Erdman Penner tracked down the endearing stray at the local pound, where she was about to be put down for the last time. Penner, on the other hand, intervened and adopted her. It ended up being one of the most important live models for the film’s animators, and the dog was one of them.
