"what are han and chewie though" han is a jack russel terrier because of his amazing propensity to cause absolute chaos wherever he goes

chewie is just a dude

"but this is a furry au" yes exactly, so that means the furry-izing ray hits the wookiee and un-furries him instead of making double furry happen. chewie is just a dude. just a regular ass human in among all this shit. don't question me, this is obviously how it all makes sense.
