Nutsy: Lady and the Tramp
Forgotten Disney Characters

Nutsy is a dog who appears in Lady and the Tramp. He is shown when Lady is in the pound, and takes "the long walk" as he is one of only a few characters to die. He is lead to a room with a sign that says "keep out". He is presumably put down inside the room.

Even approaching the room, Nutsy is shown to be happy; smiling the whole time. He stops mid-walk to scratch himself, possibly showing some naivety.
