Zwei is a gag character who breaks nearly all of the established rules of the universe, like Phantom said it's the rule of funny, as far as we know Zwei is the only dog who can do things like that because he exists to be a joke. A lot of anime actually have characters like this.The best example I can think of off the top of my head is Mako Mankanshoku from Kill la KIll but even then that's not a perfect example since she only breaks the rules of reality in certain scenes but not in others.
