I've heard a few researchers refer to Dogman as a "new thing" but really, these sightings have historical precedence. Early settlers talked about "werewolf" encounters here in the United States, werewolf clearly being a term they brought over from Europe. Did they also bring these creatures with them, or were they encountering something unknown that was already living here in the wilds?
For those interested in Dogmen accounts, Lon Strickler at Phantoms and Monsters has put up an online map listing sightings, both modern and historical, for the Pennsylvania region.
This is a great tool and I'm sure that it will be expanded on. If other researchers did the same in their areas, we could cover a lot of ground and perhaps start looking at patterns.
