I had that with my a few of my big
dogs in the past and Miss Mini...A vet told me to ignore her whenever I come in and to tell any visitors to not acknowledge her for atleast 5 minutes upon entry! It works, it really works and its funny cuz she doesn't do it when I come in anymore but will do it when anyone comes over that doesn't remember to ignore her when they come in...Its so hard to ignore her...and when guests come over they even know when its appropriate to finally acknowledge her! Shes got everyone wrapped!
