I asked my township police chief ...if a Dog comes onto your property you have a legal right to protect your livestock...I don't know about where you live I asked here...I have dogs I love dogs...I don't want to hurt anyone's dogs...that dog came back last week hunting my ducks on my property...I dispatched a.357 into the ground to scare it because I don't want to hurt it. But I don't want more dead ducks....leash laws on my sides also..My wife cried for two days after the last ducks got killed needlessly.
