We have a dog who killed 3 of our bantam sillies (silkies) and one rabbit (that got out of the coop). We have secured him for now on to the front yard and house only, but we have little kids that go in and out of doors all day long. We are always on vigilance duty. It's hard and it gets old. And one day.... So we think about giving dog away - but we can't do it. I have heard - once a chicken killer always a chicken killer. Is it true or can you train a dog? Any advise really welcome!
