I agree with Val that I also assumed the owner had tried that. I also hope we have become somewhat more "educate" about dogs and their behaviour. I believe in "old fashioned discipline as well however I also believe in using resources available to us in this day and age. My Father knew alot about animals and their behavior however, not having available to him the research etc of this day and age has shot many a good dog for fighting, biting etc. His knowledge was limited and he could not have "out of control" dogs around his stock. I just wonder how many a good dog met a untimely demise due to his lack of resources?? I really believe in dog behaviorist as well as dog psychology. I have a BS is Psychology myself and when Lady's first Daddy died I noted the same signs of depression in her ie. not eating, agitation etc that we humans experience. My Dad would probably be laughing in his grave to hear me speak of a depressed doggie. I also used some of the same techniques with her as I would use for a human ie. walks, lots of attention and understanding and allowed her time to heal and go through her own grief process!!
Just as humans act inappropriately due to some sort of dysfunction, trauma, fear etc. I also believe at times animals "act out" for the same reasons. I know some of you will thing I am way out there however this is my belief and I have seen it work with my own dog...Susan & Lady
