Missy - Lemmy

I had a cat I just called Cat, but it was short for KittyCat-o-Matic With The Four On The Floor
I’ve got a friend who had a dog named D.O.G. He’d always pronounce it like he was saying “the OG”. I never figured out whether it actually stood for anything.
Not The Notorious D.O.G.?
That’s always what I thought but never got a straight answer.
