I cannot imagine. Thankfully I have not had to deal with this yet and it's been 11 yrs. but I keep a shot gun and rifle by front and back door just in case. We did see coyote poop yesterday down on the dirt road off our driveway. I assume coyote since we know they are around. I hope you can get this issue taken care of either by better fencing or by getting someone to take care of these dogs .Oh last time he was visited by both. If it happens again I will go to magistrate judge and have him dealt with. Animal Control is always a Smart *** when they come. Getting them to come out here is a problem unless you call 911 which is what I did last time because the dog was a Pitt and growling and snapping at me when I was beating it of my birds with a pitch fork and then a 12 gage. I never got a clean shot that I wouldn't kill half my flock. It still makes my blood pressure thinking about it...
