Chibimoth is Kotori's pet in Rewrite, though calling him a "dog" is something of a joke—Kotarou and basically everyone else constantly point out that he looks absolutely nothing like one. He shows up toward the end of the Common Route and becomes more prominent in Kotori's route specifically.
Despite being tiny, Chibimoth is weirdly strong and fast, which catches people off guard. He's got a signature catchphrase—"Mosu! Mosu!"—that he says constantly, and it's pretty much his whole thing.
