My grandfather has a house up in the Upper Peninsula, and he just got done telling me about four coyote attacks on dogs just this week, two of which happened while the owner was walking the dog.. He is concerned, and wants a something to carry around in the woods to be able to defend himself if the need arose, preferably a handgun that can be decently concealed. I don't know what would be best suited for this, so I need some help. If you had to have a handgun to defend yourself in that type of situation, what would it be? If you would rather a rifle or shotgun, those could work as well, I don't want to leave any options out, he just mentioned handgun primarily.
