She is the worst dog about barking I have ever seen! She doesn't bark at meShe loves meBut when ever any one comes over, she growls and barks at them for a long timeAnd at night, when we are sleeping, if she hears a tiny noise in my apartment, she barks as loud as she can and it wakes me up and it makes me have a bad day at workShe is really lovable and sweet once you get to know herThe worst time she does it is when I take her walking so she can pottyHow can I get her to relax and be a nice dog?
