It’s obvious, really: “God” and “dog” are just two sides of the same coin. Literally any pantheon, deity, or divine force that’s ever existed - yep, they’re all dogs somewhere.
But why? What reason could the omnipotent creator of the universe have to take on the form of man’s best friend?
Vaguely plausible answers preferable. If you’re a being capable of literally anything conceivable, would you really want to be a dog?
