When Brian accidentally becomes a local hero, an old street pal - and now a successful millionaire dog - reaches out and tries to convince him to get neutered. Meanwhile, Lois gets a pixie cut against Peter's wishes, so Peter retaliates by trying to out-embarrass her.

Stewie's future life could not be going any better, living as a wealthy, old Mr. Burns-type man, until his retirement is interrupted by Brian, who brings news that Peter is dying.
