Doberman Vs. Pack of Coyotes

I have a great Pyrenees, he can hold his own. But I hear the coyotes calling, I am ready to go to work. Around here, lucky to have a 200 yard open shot. 30-150 at most, unless you want to shoot towards a neighbor. I can't lie, I shot a raccoon with a 308 for getting into my Oreo cookies on the porch one night.
