My favorite hen got killed today. A big black dog showed up to our house a few days ago. We thought wecwould let it say until its owner came back because it had a collar on and we thought it fell out of a pickup. We left early today and went shopping because the dog left and we thought we had nothing to worry about. We came home and saw the dog again. When I went to go collect eggs, I found my little girl. I was so mad I slapped the dog and chased it away. I think it will come back though because it went a few houses down. Can I please get advice on what to do about the dog. I'm thinking if it comes back to shoot it even though it belongs to someone, I just don't know.
