I went through this about a week ago. I called the sherriff.....you know what he told me!?? " If they are killing your chickens, get a gun, and put it to it" I told him I didnt think I could shoot the dog, but MIGHT be able to trap it in a large pen. He said.. " If you trap it, call us, we will come shoot it" I did get a gun...but the dog has not been back. This is not the black lab that previously killed here. This one was LARGE, probably 150 pounds, Looked like a wolf mix. Big, brown/grey, and shaggy. Im just glad it hasnt come back! Im so very sorry for your loss. Its soo tragic to lose ANY. PLEASE, call the police, and get a report made....for YOUR protection! These dogs WILL be back.
