My wife had her girlfriends over for a girl thing around the fire with wine and their dogs. My chickens were all out. I told them the chickens were out so they needed to keep their dogs close and not let them roam too far afield. One woman's dog, a German Shepard mix, kept roaming farther and farther away. Every couple minutes, I kept saying, "Kathy, call your dog back. I don't want it to attack my chickens". Her repeated reply was, "Oh, he won't do anything". I said, "Kathy, it's a dog. When the chickens run, he'll chase them." Her reply "Oh no he won't, he'll be fine". I said, "Kathy, don't make me shoot your dog. Call him back now or I'm going to grab my shotgun". She was incredulous and said, "You wouldn't shoot my dog and they're just chickens". So I got the shotgun and went back by the chickens at about the same time the dog ran at one of the flocks of chickens, cornering them. Luckily, they managed to fly over the fence before he could grab one, even though he tried to. It was total mayhem. To this day she doesn't understand why I would kill her dog nor the value of extremely rare chickens. She's a chef and cooks chicken all the time and doesn't know about anything other than Cornish cross and eggs.
She still says she doesn't believe I would have shot it and I continue to tell her I would if it killed one of my chickens.
Just how many times does a dog owner need to be warned? I pleaded with her a dozen times to control her dog over 20 minutes till all hell broke loose.
