Only adult humans are legally permitted to sign the NDA that <<<NASA>>> makes you sign when you “go to space”. Dogs are not adult humans. The “moon” is in “space”. Therefore, <<<NASA>>> would never allow a doggo to go to the “moon”. I daresay that whatever you pet on the “moon” was definitely not a dog. It could have been a robot, or a man in a costume, or an alien space craft, or a Guatemalan that illegally crossed over the ice wall, or many other things.

There’s no way it could be a dog.
