Something I'd like to add about the boxed game (not necessarily the one the dog programmed)

The exact same game sprite was in the MTT news, as the video game you can report for the news. So the boxed game does indeed canonically exist within the world of Undertale. And since Flowey doesn't know about the events of the Pacifist Route beforehand, said game likely ISN'T Undertale either.
