So I looked into Dogman...again. It seems the skeptics are mostly right about this one. While strange reports of doglike creatures are as old as civilization, the modern Dogman seems to be a piece of emerging folklore which can be traced back to an April Fool´s Joke in 1987 (Michigan) and to Linda Godfrey´s article on the Beast of Bray Road in 1991 (Wisconsin). Godfrey´s subsequent book (published in 2003) plus the Internet popularized the Dogman and also "streamlined" him.
Previously, there wasn´t really a single Dogman phenomenon. Now, there is. The creature is virtually always depicted as large, bipedal, intelligent, extremely dangerous and obviously canid. It´s also a flesh-and-blood creature. Finally, note the difference between Dogman and werewolves: the latter are said to be humans who can shape-shift into standard quadrupedal wolves.
Of course, a paranormal explanation is also possible, and the Dogmen would then be fairies taking whatever form we expect them to...
Can you look specifically at the earliest Bray Road reports and list what each witness actually said about whether the creature was walking on two or four legs?
