The Littlest Hobo

I saw this movie in a theater in Nebraska when I was a child. Don't recall much about the movie itself this many years later, but I've never forgotten that day. It was my first brush with celebrity. The dog star of the movie (we were told it was THE dog) made a personal appearance at the theater. The dog performed a number of tricks on stage, even typing on a typewriter. I came away with a paw-printed glossy photo of the dog, which I kept for years. I wonder if anybody else out there got to meet The Littlest Hobo in "person." I've never seen the film since, and didn't know till I looked it up on IMDb that there had been a television version. It remains among the most lively of my black and white memories.
