The recipient of this curse is haunted by the distant sounds of a howling and barking dog. The victim will always hear the dog at the most inopportune times, while trying to hide, fall asleep or concentrate on some task for example.
This curse grows in power and intensity over the course of time, beginning as an occasional faint howling or barking. After a few weeks this will escalate to regular barking, baying and howling just out of sight. The curse is infectious. Those that associate closely with the victim can themselves become victims, especially if they attempt to help the victim find the source of the barking and howling. Avoiding the curse is a Good test of resolve.
Any attempt to find the source of the curse's noise leads the victim on a wild goose chase. The sound will always come from just out of sight, and randomly shift locations to throw off pursuit.
The curse can be identified with a Superb test of divination magic. A Great test of dispel magic is required to remove it.
