Famous Four legs butt-sniffer

[[HKG]hkwh01]

My native are not english , I have little knowledge about the name and species of animals in english . I have searched the web and then I know the answer .
But is it possible to find it out just in the game? The hint is not so clear , I have guess dogs Dogs dog Dogs cat / rats/ mouse/ pigs / ♥♥♥♥♥ ..etc , all wrong .
The notice said the password changed back to the original , logically the password would not be the same as the hint .. isn't it?

Passwords:
Pluto, Snoopy, Oddie, scooby doo...

i'm just suprised why Laika (first dog in space doesn't count as famous?) isn't a vaild option.

Doge is a valid option :P

I don't know if you have figured it out, but doc_disposal->retrieve gives you more strong hint. I won't give you how to do that exactly, but ask me if you definately need some help.
