Nice try, Glowsquid. You can't brainwash me into believing Spitz of all characters was born a dog. Just look at him striking that animu cat pose. Look at his whiskers. His squished little cat mouth. That impossibly articulate tail.
This little shit isn't a dog and I don't appreciate your species denial propaganda, Glowsquid.
The only theory I'd be willing to tolerate is that perhaps our dear furry friend Spitz is a trans-species cat, or the reverse, whatever the fuck correct terminology for a tranny is, but such a theory has a snowball's chance in hell of being true given Takeuchi's known hatred for trans-spec. furries. Shame, considering all the progress made in Gold with its interspecies sex scenes.
Come on, Goro Abe. It's 2019. Give the writhing SJW worms what they want.
