ok I just found this out not to long ago,a can of wasp spray is just as good if not a little better than mace as it will temporarily blind the one that gets sprayed, with all the breaking around here lately we have one that is handy for us and you bet I will use it .Another thing that might be a good idea to get is a tape recording of a BIG dog barking that was another suggestion to help protect your home.I would also post the non emergency police number right somewhere anyone can find if you feel calling 911 isn't a option. Personally you should call them this day and age anything like that is more an emergency than it has ever been before
