I remember seeing a Monster Quest episode on the History Channel about those strange Canines.
They did extensive DNA and tissue analysis, I'm kind of tired right now, so the end of the show is a bit foggy but I remember hearing it was not
Mange but a Hybrid, between a Domestic dog and a coyote.
Something along those lines, check the monster quest site, maybe the episode is up on the site.
