Wulv

During the Harvest Moon festival, many pups tell tales of Wulv, a large fox spirit that emerges from a large root in the ground to hunt small pups. The only way to avoid his teeth is to dress up as something else. Whether the costumes are so Wulv does not recognize them, or to frighten him off varies with each tale.
While the stories aren't true in the slightest, Wulv thinks it is funny that the pups think of him as a scary story, it certainly doesn't help that he sometimes follows along with the stories to scare any mischievous pups who steal festival treats from the others.
