Beware. Well, it came to my attention that there was 1958 pilot
The Adventures of Super Pup that thankfully never aired.

Where it was about a dog person that did the Clark Kent/Superman role. The costume was worn by a little person Billy Curtis who was the star of "
Superman and the Molemen".
More about it on:
Xoomer.Alice on the Adventures of Superpup
Like I said scary.
