We have a 9 week old olde english bulldogge we got about a week ago. The only behavior we have seen that is concerning us is she will occasionally bark and growl at us when she is tired (we know she is tired because when she calms down, she will fall asleep right away). We have tried different methods including ignoring, gentle "no's", firm "no's", and physically dominating her until she relaxes. All have worked at least once but none seem to consistently work. We would love any advice on how to train this out of her.
