Supposedly, to us, none, although I've heard anecdotal stories of deer hunters being treed by wolves. The dogs are another story--Wisconsin has multiple dog deaths due to wolf attacks each year (some occurring right in backyards
). The state doesn't keep as close statistics for dog/coyote clashes, but I've heard (again, anecdotal info) of injuries and in one case a fatality after run-ins with coyotes. Not sure what the statistics are like for Canada.
