Keishara Canaan, Vermont 1/18/2013 3:29:31 PM I have a two year old pure bred black lab. Whenever she sees people she does not know she barks and will continue to do so the entire time the are around. If she isn't barking then she is muttering and will not stop until they leave. I have tried bribing her, distracting her by talking to her but neither have worked. I do not know what to do. Could you help me?
