OK we all know that in the later years there was a huge dog (in disguise) that was initially named "Woof Woof" and later was changed to Barkley. I could have swore in the early days there was what I thought was a real short lived real dog named Rufus. I'm not sure who he belonged to but I think it was Susan and Gordon's dog. Did a dog by this name actually exist on SS or was I thinking of another show?
