 In the climax of the picture, Jock and Trusty bring down the dog  catchers wagon, with Tramp inside. After this, Jock discovers that  Trusty has been injured and pinned under the wagon. Jock is very sad  because Trusty was originally supposed to die in this scene. That is  why Jock nudges him and he does not rouse. When Walt Disney viewed  this scene, he was shocked. Walt did not want a repeat of the  traumatic scene in _Bambi (1942)_ (qv). He thought it was too  intense. Walt then made the animators put Trusty into the end  Christmas scene to reassure the audience that Trusty was simply  knocked out and injured in the previous scene.
