Is there a cheat code for Fable 2 that revives the dog

No, there are no cheat 'codes' for fable 2 only hints. If you want you dog back you have to choose the 'loved ones' option at the end of the game.

The Hearach is right, there are no cheat 'codes', and choosing the 'loved ones' option WAS the only way to revive your dog. But if you download the Knothole Island game add on you can revive your dog using Cheet Urs crypt, or something like that.

It is a crypt that allows you to revive your dog if you sacrifice a human, its located just near the entrance to Knothole Island village, if you turn left after the dock youll see it.
