Hogs are not too established in Michigan yet. Here is some info on feral swine in Michigan, they can be shot onsite at any time of the year. http://www.michigan.gov/dnr/0,1607,7...230---,00.html

Here is a map of where they have spotted and killed in Michigan.

Your best bet if you really want a hog is to go to a game ranch in Michigan that has them. That is how we have some wild ones now running around.
