Plenty of wolves in the Western U.P. I've heard anecdotal reports of concern about wolf danger to dogs. Seems like the stories most often involve hounds that are not in proximity to people (e.g. running bears, for example). Wolves are apparently VERY territorial and male dogs are seen as competition. I've never had a problem, but I "carry" when I'm working my bird dogs. There have also been incidents of predation on domestic livestock.
Don't think people have much to fear from wolves. Since states now have authority to manage wolf population, the DNR can deal with them if they become a problem. Wolves add to the mystique of the U.P. I've only seen one.
