So, I have this wonderful Border Terrier who is great with the chickens. He's not the least bit interested in them. They have been sharing the same space all spring and summer without a single incident. However, I just got an adult rooster who tries to attack the dog every chance he gets. Yesterday, the poor dog snapped after being ambushed by the rooster. He had the rooster by the neck and pinned to the ground. He let go when I told him to. 30 minutes later the dumb rooster was at him again. This time the dog ran away because he didn't want to get in trouble. One of these days the dog is going to defend himself when I'm not there and he's going to kill the rooster. Then he might decide killing chickens is fun and my days of free-ranging will be over. Is it possible to teach this rooster to leave the dog alone or should I get rid of the rooster before he spoils everything?
