The name Zwei is definitely meant to reference Ein from Cowboy Bebop. Like Ocomfv said, Eins is German for one, and Zwei is German for two. Ein is a corgi, Zwei is a corgi. Monty's friend Johnny has a tricolor corgi (the one in the photo that Ocomfv provided) named Junkers, Zwei is a tricolor corgi, and Monty seems to love corgis.

Whether or not Zwei alludes to Toto, though, I dunno.
