There was also Lassie, Wishbone, and Bear (the chimpanzee from BJ and the Bear).
In Canada, we had The Littlest Hobo. He was a dog of many names, though his "real" name was London.
About two years ago my husband recorded a Mr. Ed episode. We laughed so hard because it was so silly. I keep meaning to try and find some more to record. I can't recall the whole episode but Mr. Ed was surfing - lol
