In the climax of the picture, Trusty was originally killed when hit by the wagon. 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. 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.
