Woof Woof Story: I Told You to Turn Me Into a Pampered Pooch, Not Fenrir!, Vol. 6 (light novel) - Kochimo Inumajin

A series of unexpected events has brought yet another general of the Demon Lord into the employ of the Faulks mansion…Belgor, formerly disguised as the holy sword, is settling into his new post as a kitchen knife. It’s looking like it might be a while before Routa’s life returns to normal. In fact, it’s almost as if everyone’s forgotten his role as the family pet, seeing how he’s called to search for missing pups and fight against evil with Alstera in the Royal Capital. But when the mansion faces a water shortage, Routa is among the first to volunteer in the search for answers! After all, no water means no baths, which is unacceptable! It looks like another of the Demon Lord’s minions might be responsible for this…but it’ll take more than their army of generals to keep Routa from living his best pet life!
