Before I got chickens (and chicks) I was very concerned about my three Pugs and the Chihuahua either picking on the chickens or the chickens pecking the dogs and putting an eye out or something. Turns out these fears are unfounded. The chickens free range in the yard, where the dogs have total access. The Chi finally gave up trying to smell chicken butts and form friendships...the pugs all just ignore them. It is not unusual for eleven chickens and roosters to be in a flock including the four dogs with all of them just a few feet from one another. I figured this was because all my dogs are small...but I have a friend who has two huge mixed breed dogs each of which goes over a hundred pounds and they will lay in the yard when her chickens free range and not even move when a chicken comes near.
