Loyalty is what a dog provides. The ancient joke-name for a dog, Fido, is in truth the most perfect of all dog names - I am faithful. I am loyal. I remain.

as for fido dido (who's no longer a dog, though i thought all along that he's a dog!), well, an internet search gives the simplest meaning of the classical latin dido--in turn taken from classical greek--as "trick or joke".
for the dog fido, please go to the thread of the same name in "history", this forum.
