Has anyone had a dog who chased and attacked chickens? If so, what did you do or how did you get them to stop? We have a new dog that seems to be obsessed with watching the chickens in the coop and yesterday he got out and my chickens were free ranging the yard and he went after one of my girls and has his mouth on her and feathers were everywhere. I was able to catch him in the act and get after him but he still seems obsessed. He is a newfoundland. Any ideas or advice on what to do to get it through his head that this is a no-no. My border collie does not do this at all. She actually got after him! HELP!!!
