Arthur's dog Pal gets sick and they sent him to the vet where he has to stay there overnight leaving the two apart not knowing if Pal will be all right as Arthur is left incredibly depressed not making things any better is D.W. who acts incredibly insensitive towards Arthur's feeling with her saying now they can get a new dog and later brings up about her pet Spanky who died in a previous episode which which causes Arthur to whimper in a very unsettling way before calling out to mom.
